Presbyopia is a condition that disproportionately affects people who are over the age of 40. Without going into a lot of detail, your eyes harden, which makes it harder to focus on objects at certain distances. To remedy this situation, bifocals were created. They allowed a person to look through part of the lens to focus on closer items while being able to use a different part to focus on things farther away. Today, this same concept has been extended to contact lenses. In general, they fall into a category known as multifocal contact lenses. There are a number of different types of these lenses available, so here is a quick introduction to what they are and what options you have.

Multifocal contact lenses are essentially bifocals in contact form. They do not have any delineation lines like bifocals do, but are designed based upon the same concept. However, there are a number of different ways that your contacts can attack this problem. The two main decisions that you will have is what type of materials you want the contact lenses to be made out of and what type of correction technologies is best for you.

Of the materials available for your contact lenses are soft lenses, GP, and hybrids. Soft lenses are just like traditional daily wear lenses. They are disposable and can be for daily wear, weekly, or even monthly. While some can be worn overnight, it is rarely recommended. The next type are known as GP lenses. They are made with a semi-firm material so that it keeps it shape at all times. While this can make them less comfortable, they are still effective. Plus they are smaller, which makes them appealing to some. The find type are known as hybrids. They have a rigid middle, similar to a GP, and a flexible outer area similar to soft contacts.

The next option made available is that type of corrective technology that the contact lenses will use. The three most common options are concentric bifocals, alternating image design, and simultaneous image design. Concentric bifocals are fairly simple. The center portion helps you see close up and the outer portion helps you see things that are far away. Alternating image design (translating design) are only available in GP lenses and have the distance portion of lens on top and the close-up portion on the bottom (just like traditional bifocals). The final option is simultaneous image design. These lenses can be either soft or GP. They place both the near and far powers across the center of the lens so that you are can focus on both simultaneously.

While these options may seem a little overwhelming at first, your optometrist should be able to let you know which ones will be viable for your specific needs. From there it is simply a matter of trial and error until you find the one that feels the best, while also correcting your vision. While there are a number of additional details to keep in mind when looking for the right type of multifocal contact lenses to meet your needs, this quick introduction should help you get started in the right direction.

Hello and welcome..

Today we are going to discuss the screen display system on any Toshiba laptop.

All Toshiba laptop screens are housed within a shell that is the lid which on the majority of the model range is Plastic ABS. Some lids were made from cast aluminum (Some Porteges).

The screen though is mounted to the lid using a system of rails, these rails are mounted to the lid. There are many rails systems employed in Toshiba Laptops, and some are interchangeable with other laptops, notably the Toshiba Satellite Pro 6000, Satellite pro 4600, and the the Satellite Pro 2100/1400/2410/1410 Series Laptops as an example.

Screen rails are usually constructed of pressed steel to fit the profile for a given size of screen and to enable fixing to the base lid.

The rails are fixed usually by small screws although on some Toshiba laptops you may find that there are no rails actually fitted to the screen the lid becomes the sole mounting site for the screen.

The front bezel is made from plastic ABS, this is a flat plastic cover which conceals the rails, the screen inverter and protects the screen area from ingress and dust penetration. the bezel is moulded in such as way that it incorporates many snap lugs around the periphery of the bezel reducing the need for lots of fixing screws, the lugs will locate and lock the bezel into place. Some older machines used this combination of snap lugs and fixing screws (for example the Tecra S1 series laptops). Most modern Toshiba Laptops use the snap lug fixing method since it is cheaper to manufacture and also reduces weight and component count.

For machines that were tablets there was slight departure from the standard design because of the complexity of the touch screen and the extra weight that these extra components when assembled. With many tablets the design of the lid and the front bezel were different to accommodate the feature of rotating the screen through 360 degrees and the newer style of fold flat lids which when lifted up, and then rotated, enables the display facing upwards, resting on the profile of the main base.

The basic components of most screen display systems are,

The Screen
The Screen Connecting cable
The Invertor
The Base lid
The Hinge mechanism
The front bezel
Any wireless or Bluetooth cable systems
Lid latch and return spring assembly

I won’t discuss the exact technicalities of tablet screen systems because Toshiba did not really standardize between models so it does not merit any further discussion here.

We have already touched on some of the elements of the screen display such as the lid, the screen rails and the front bezel, I will now move on to the invertor and the other system components.

The invertor primarily functions as a lighting up circuit, its function is to supply energy to the cold cathode display tube that is manufactured at the bottom of the LCD display, this provides a back lighting system so that you can see each and every pixel being displayed on the screen without it the screen would remain dark. More modern machines have much more advanced electronics fitted into the design of the invertor, such as screen brightness settings, current overload, screen blanking, sleep adjustment and various other attributes of which includes bios control as well.

Some screens which are high definition are fitted with two invertors to increase the overall contrast and brightness of the screen and to distribute the power required by the screen tubes evenly. These are usually fitted to screens of size of 17″ or larger.

The screen connecting cable comes in four standard sizes, and is dependent on the capabilities of the screen fitted, its resolution and its overall size, the cable will supply all the control signals and power lines to the screen interface, detection of the screen type, and the actual display data to the user. The most common cable now found are the 30pin flat connector which is actually a very low current signal propagated at very high speed and then reflected back into the main system, commonly known as LVDS, we won’t discuss the technical details of this system its beyond the scope of this discussion.

The cable is connected at the other end to a graphics card switching circuit which enables the user via software or hardware detection to determine the default type of display device. If you plug in an external monitor some Toshiba laptops will default to displaying on the external monitor rather than on the LCD screen.

The hinge mechanism is an assembly that maintains the integrity of the base lid system and enables the user to adjust the screen position in on dimension, the criteria here is maintain an adequate force to hold the screen upright for extended periods of time and at the same being able to close the lid easily and without any notchiness or serious restrictions. The design on many Toshiba laptop hinge systems falls into three categories.

Lid and hinge integrated onto the palmrest
Lid and hinge detaches from the palmrest
Lid detaches form a fixed hinge system on the base

Most modern Toshiba machines now fall into second category, though I feel the first category was actually the most durable, this can be seen on the Toshiba Satellite Pro 2450, Toshiba Satellite A40, Toshiba Satellite Pro 4600.Most Toshiba laptop hinge systems comprises of a cast steel pin with an outer sleeve pressed onto the outside to create the friction necessary to force the screen to remain upright, the other end of the pin is then machined with a spline which then is force fitted to the hinge surround, the hinge surround can extend under the palmrest and is then fixed to the palmrest (as in the first category) or detachable as in the second category. The hinges also form part of the lid support system with a continuous bracket system extends to enable the lid to be mounted to the hinge assembly, cutting down excessive components and weight. The more modern systems comprise of a cast post material, inserted to the base system and then fixed from the back and the undersides with screws, the hinge itself is part of the cast post system and the spline is inserted into the cast post with tremendous force, the restrictor sleeve is then mounted to the lid frame, this is the more common in the second category. The third category is not much used these days except for very small light weight laptops where weight and size dictates the screen hinge components.

The lid latch system is a simple latching assembly pre tensioned by a small cylindrical spring, allowing self retraction of the screen lid locking jaw, these are usually a claw shaped plastic component that locks into the base system. Most Toshiba laptops have used many variations of this construction and its proven reliable, since all Toshiba lid plastics and hinges components are very accurately made, alignment is maintained even through excessive wear of the hinge system or accidental damage to the lid. This construction also reduces wear on the lid locking jaw itself, the locking jaws primary function it that its strength relies on the width of the jaw and the length of the jaw when in the locking position. More modern machines are now moving to the lockess style of construction but the palmrest design and the top lid has now been redesigned to give a perceived and noticeable incline to enable the lid to remain closed (clam shell design). 

Wireless cable systems are usually attached behind the screen on the lid base, their primary function is to provide a larger surface area in which to receive the appropriate wireless signals, this also applies to blue-tooth cable systems as well. Most wireless cable systems are usually an RF self adhesive pad this enables the service technician to easily replace a damaged cable.

Well That’s it for now!

Getting familiar with recordable DVD formats

Probably everyone nowadays had a need to transfer information between several PC’s or make a backup copy of favorite movie. Recordable DVDs (DVD-Rs) serve this purpose very well, but it could be quite hard to get familiar with all the different types of them. While in CD era there were only two formats, namely CD-R for recordable and CD-RW for rewritable disk, for DVD it is not that simple. The fight between manufacturers to enforce their own formats led to the mess of the biblical scale. Besides DVD-R and DVD-RW, in most shops it is possible to encounter DVD+R, DVD+RW and even mysterious DVD-RAM. And there is no guarantee that your DVD drive will be able to work with newly purchased disk.

In this article we will try and help users to get familiar with this mess.

DVD-ROM

(DVD Read Only Memory). Generic factory-printed DVD. All mass-production DVDs with movies, software etc are printed on DVD-ROM.

DVD-R

(DVD-Recordable – pronounced as “DVD Are” or “DVD Dash Are”). This is the first format for recordable DVDs. It was developed in 1995 by Pioneer and was approved by DVD-Forum as a main standard for recordable DVD. Basically, this formatis direct analogue of CD-R but with bigger capacity and, respectively, smaller track size. As with CD-R, record is made by altering the structure of organic polymer in reflective layer with powerful laser. DVD-R can be recorded only once, but it is compatible with most DVD players and computer DVD drives. Properly stored and unscratched DVD is believed to remain readable for hundreds of years.

Initially DVD-R was only single-layered, but recently double-layer DVD-R DL (dual layer) becomes available. They are also known as DVD-R9, however, they are still uncommon and they can be recorded only on newest models of DVD burners. Trying to record these disks in non-compatible drive can actually lead to the DVD burner damage.

There are two types of DVD-R disks: DVD-R Authoring (DVD-R (A)) and DVD-R General (DVD-R (G)).DVD-R (A) type of disks appears first and was used only for professional needs. This type of disk allows recording of anything, including hidden area and keys, which means that It can be used as a master-copy for mass-production.

Devices and disks compatible with DVD-R(A) are professional equipment and therefore very expensive and uncommon.

DVD-R General (G) is much more common. It was developed later specifically for the needs of common users. This type of disks does not allow making a full copy of protected DVD – no keys will be recorded and resulting disk simply will not play. On the other hand, there are lots of devices and blank DVD-R son the market for this type of disks, and they also quite inexpensive. DVD-R (G) devices can read DVD-R (A) disks but cannot record anything on them.

Unlike CD-R, DVD-R shave a special copy protection called CPRM, which stands for Content Protection for Recordable Media. Each blank DVD-R has inerasable encrypted entry (lead in) in hidden area of the disk, which contains information about type of medium and manufacturer. When backup copy of protected DVD is made, copy program will re-encode the information again, but this time using this hidden information, so twill not be possible to copy the resulting disk again as it will require hidden information from specific medium. This type of copy protection also supported by other DVD-Forum formats, namely DVD-RW and DVD-RAM.

DVD-RW

DVD-RW (DVD ReWritable) was also developed by the Pioneer and essentially is the same DVD-R with only difference that reflective layer’s state can be transformed by the laser more than once. The specifications for DVD-RW states that each DVD-RW medium should withstand up to 1000 rewriting cycles. The reflectivity of DVD-RWs is much less then of DVD-R and some DVD drives can mistake them for dual-layer DVD. For this reason DVD-RW are compatible with only approximately 70% of existing DVD players.

Early models of DVD-drives required DVD-RW to be finalized in order to read it properly; however, with the appearance of new drives this is not necessary anymore in most cases. It is also not necessary to write at least 1 GB on a disk. Files of any size, no matter how small can be recorded now.

Dual layer DVD-RW, called DVD-RW DL with capacity up to 8.54GB of data is about to appear soon. Currently it is being developed by Ricoh; unfortunately, it won’t be compatible with current DVD-drives and for this reason is unlikely to ever become popular. Besides, high capacity Blue-Ray and HD DVD are also coming soon.

DVD+RW

Despite the decision of DVDForum, DVD+RW (DVD ReWritable, pronounced as DVD plus R) format was founded and promoted by coalition of developers called DVD+RW Alliance. First version of DVD+RW, presented in 1997, was able to hold only 2.8 GB of data (compared with 4.7 for DVD-RW). These disks also weren’t compatible with normal DVD players and, basically, all of these were the reasons for DVD Forum not to accept this standard.

later developers managed to improve both flaws but even after this, DVD+RW didn’t become a standard. As a result, DVD+RW can only reviewed a potential alternative to DVD-RW. However, DVD+RW is not without some pleasant features that DVD-RW misses:

1. Lossless linking technology allows editing of the recorded disk on sector level, which means that, unlike in DVD-RW, there is no need to rewrite whole disk when only certain parts of it needs to be changed.

2. DVD+RW format has better facility for error handling. If certain sector wasn’t recorded properly, it is rewritten again, more carefully. Also during the process of disk creation DVD Burner is able to determine the address of sector that is being recorded, so if the record process is interrupted, it is possible to resume it from the same position where it stopped.

3. DVD+RW format supports EasyWrite(Mt. Rainier) technology, which in conjunction with special software such as DirectCD or InCD allows using DVD+RW medium as a normal floppy or hard drive via Explorer or other file manager. The support for EasyWrite also will be included in new Microsoft Windows Vista as a standard option.

4. In addition to everything above, maximum writing speed for DVD+RW is about twice faster than for DVD-RW.

However, DVD+RW format also has some drawbacks.For example, DVD+RW is less compatible compared to DVD-RW, and the probability of running into incompatible DVD drive is higher, no matter what the press-releases and advertisements claim. Compatibility becomes even bigger issue for old DVD drives.

DVD+RW and DVD+R have a special protection system designed for them, called VCPS (Video Content Protection System for DVD+R/+RW). It has all the features of CPRM (which is for DVD-RRW) and also supports limitations in copying of protected digital broadcasts. However, such innovations are usually welcomed only by movie and video producers and generally provide only nuisance for users.

DVD+R

Although it might seem strange, DVD+R was introduced by the same DVD+RWAlliance later than DVD+RW, namely in 2002, which is the reason why it is possible to encounter DVD drives that can work with DVD+RW but are totally incompatible with DVD+R. The introduction of DVD+R was more of a step back for the developers, as the only thing they have to do to create DVD+R is to change the substance in reflective layer of DVD+RW from rewritable to the one that support only one cycle of writing. Due to this, DVD+R is actually missing some of useful features of DVD+RW, such as improved error handling. There is also dual layer version of DVD+R, called DVD+R DL or DVD+R9 (actually, it appeared earlier thanDVD-R9). In general, DVD+R does not differ much from DVD-R.

DVD-RAM

Initially DVD-RAM (DVD-Random Access Memory) was developed for back-up storage, but later it’s capabilities in handling video became evident, so now there are many home DVD-RAM camcorders and DVD-RAM recorders which are aimed to replace VHS.

Although DVD-RAM format was developed by Panasonic in compliance with DVD Forum, it is much different from DVD-R and DVD-RW. The chemical part of the process is essentially the same as in DVD-RW, but the logical part more resembles the operation of hard disk drive. From the very beginning DVD-RAM is divided into several sectors. Data is recorded not in circular track as in normal DVD and CD but is directed in certain sector, without particular order. During reading of the disk this allows to find the desired file fast and easily by addressing appropriate sector. Besides, this layout allows reading and writing information simultaneously. Interestingly enough, DVD-RAM does not require any special software for recording; it can be accessed in the same manner as normal hard drive or floppy disk.

Although DVD-RAM can withstand more writing cycles (about 100000) than DVD-RW, it is substantially more fragile and have to be handled with much greater care. For this reason many DVD-RAMs are being sold in special cartridges, however, if disk is single-sided, it can be removed from cartridge temporarily as some DVD-RAM recorders have normal CD tray instead of cartridge loader.

Some DVD-RAM disks are actually sold without any case at all. These disks require extreme caution during use.

However, despite being extremely fragile, DVD-RAM has most reliable error checking. If error is discovered during burning process, data is simply recorder in different sector; while in any other DVD format disk will become completely unreadable.

Speaking of compatibility, any DVD-RAM recorder will have no troubles reading DVD-R and DVD-RW formats. However, only few drives will be able to read DVD-RAM format. Unfortunately, DVD-RAM is much less common compared to other formats of recordable DVD‘s and therefore the price for both drives and disks is still relatively high.

DVD+VR, DVD-VR

DVDs can be recorded in two modes – Video Format and Video Recording Format (DVD-VR). First one is compliant with DVD-Video standard and is compatible with any equipment (this format is used for factory DVD-Video disks and for video data on DVD-R). DVD-RV mode can be altered after recording and does not require copy to hard drive in order to edit disk contents. It is possible to add, cut and delete video data for the disks written in DVD-VR mode, it is also possible to add more chapters or change menu. This can be done for both DVD-RW and DVD-RAM (for DVD-RAM it is actually the only available mode).

For DVD+RW there exists slightly better version of DVD-VR called DVD+VR. Some of the positive differences from DVD-VR are the possibility of creation of full-fledged menus up to 30megabytes in size, while DVD-VR can only generate standard play-lists. It is also possible to delete data from DVD+VR anytime, while in DVD-VR it has to be done only prior to recording of new data. And the most important thing – DVD-VR disks can only be played on DVD Burner or home DVD Recorder, while DVD+VR can be viewed on any device capable of reading DVD+RW.

Not long ago the selection of preferred format was an important question, as after selecting, for example, DVD-R compatible device the user have to live with the fact that the device won’t be able to read or write DVD+R. It was also dangerous to use DVD-RW or DVD+RW as a floppy to transfer data, because, unlike CD-RW, there was a chance that there will be incompatible drive in other computer.

Luckily enough, these problems are now gone.

Summary

After the appearance of first multi-format device on the market, any modern DVD drive now supports almost all of available formats, and the selection of desired type of DVD can be made several times a day, depending on particular task. The only sad thing that the mess with DVD formats was sorted too late, as completely new formats of disks are already emerging.

Do we really need more capacity?

Cynics amongst us may say that it’s just another way for the computer and consumer electronics industry to sell us all something new. While there is an element of truth in this, as not everyone needs the additional capacity but computers, software and applications do continue to be increasingly data hungry.

Many users will welcome the additional amount of storage that both formats offer, as they are getting to full capacity with DVD and are starting to need multi-disc sets. The new formats will be the equivalent to five and ten times the size of a DVD. In addition to this, faster broadband speeds are allowing users to download increasingly larger amounts of data.

High definition television will begin broadcasting throughout Europe in 2006 and will allow consumers the best possible television experience in both watching and recording. In the United States over seven million digital televisions have already been sold and Europe is not far behind. In Europe, it is expected that broadcasting the World Cup in 2006 in high definition and will be a major factor for many to make their first purchase of a high definition digital television.

The fast transfer rate of blue laser disc – coupled with the larger capacity on a disc – also makes it ideal for archive applications, medical records and high resolution assets that need instant access or retrieval.

First of all, let’s take a quick look at the differences between the two formats that both utilise blue laser disc recording:

Blu-ray

Blu-ray is backed by over 100 companies who are members of the Blu-ray Disc Association (http://www.blu-raydisc.com). The key members include; Sony, Pioneer, HP, Dell, Philips, Mitsubishi Chemical, Walt Disney, TDK, Hitachi, 20th Century Fox and Apple.

Initial storage capacity of a Blu-ray disc will be 25GB (or 135 minutes of high definition film and two hours of bonus features in standard definition quality) for a single layer and 50GB with dual layer (or three hours of film and nine hours of bonus materials). Prototypes have already been developed by TDK that will take this to 100GB on a single side. The Blu-ray group estimate the technology will be viable as a format standard for 10-15 years.

Similar to CD and DVD, Blu-ray discs will be available as once only recordable (BD-R), re-writable (BD-E) and in a pre-recorded disc format (BD-ROM). There will also be two other types of Blu-ray disc that are contained in cartridges for specific use in the broadcast and data archiving industries. These are called PD and PDD respectively.

Blu-ray disc products will be launched to cover three major application areas:

1. Desktop computer use and home video applications.

2. Professional broadcasting.

3. Professional data backup applications.

Blu-ray discs are manufactured using a single disc substrate, with the recording layer very close to the disc surface. This should result in less potential distortion, higher precision and shorter production times and costs.

In terms of backward compatibility, it is likely that Blu-ray disc products will play both DVD and CD formats. It is also expected that Blu-ray PC and Mac recorders will also be able to record onto CD and DVD discs. Sony have recently announced that their next generation Playstation 3 console will have Blu-ray capability.

High Density DVD

There are fewer companies in the HD-DVD Promotion Group (http://www.hddvdprg.com), but still some significant ones none the less. Companies include; NEC, Toshiba, Sanyo, Thomson and Universal Pictures. The format is also supported by the DVD Forum.

Initial storage capacity is around 15/20GB, 30/32GB and 45 GB as a maximum with dual layer. In its present shape, the capacity is unable to go beyond that due to the position of the recording layer, which is further away from the disc surface.

Disc manufacturers will be able to transition over to HD-DVD more easily as it is a similar disc structure to DVD. However, the limited capacity could see it end up as an interim solution and manufacturers will inevitably need to invest in Blu-ray production lines.

Like DVD, HD-DVD disc is manufactured by bonding two surfaces (substrates) together. It is likely that HD-DVD devices will also be able to play DVD and CD content. Discs will be available in a recordable (HD-DVD-R), re-writable (HD-DVD-RW) and pre-recorded version (HD-DVD-ROM).

89 film titles will be introduced in late 2005.

Why can blue laser expand capacity?

With the same disc surface size as both CD and DVD a blue laser disc can record and store more information by using a laser beam with a much smaller focus than CD or DVD. This laser can record smaller and higher density pits, enabling more data storage.

A closer look at Blu-ray

Within the Blu-ray family there are three types of discs available, which are optimised for specific applications. The main demand and usage will be for the standard Blu-ray product, but there are also two other types of Blu-ray discs available that have been specifically developed for the broadcast and data storage market:

Professional Disc (PD)

PD has been developed specifically for the news gathering and broadcast markets.

Products are already being introduced by Sony. These include; a recording and editing system – ENG (Electronic News Gathering) – as well as the XDCAM series of professional camcorders.

PD has a faster data transfer rate, 72 Mpbs as opposed to 36Mbps, than the standard Blu-ray product and is seen as a replacement for traditional tape loaded broadcast cameras.

The disc is re-writable and contained in a cartridge for added protection in field use. PD disc media is being manufactured by both Sony and TDK.

Professional Disc for Data (PDD)

PDD has been developed as a replacement for traditional magneto optical (MO) applications, such as data juke boxes for online or archive access and storage. PDD is physically almost identical to Professional disc (PD) and is available as re-writable and recordable. The disc is contained in a cartridge for protection and ease of use by the robotics in any juke box or library system. Typical users will be medical, banking, government and telecom businesses who need fast network access to large amounts of data or information.

Standard Blu-ray

Standard Blu-ray will be the main Blu-ray product for mass use in consumer recorders and players, PC drives and games consoles, such as PlayStation 3. The disc media can be supplied ‘naked’ and is not contained in a cartridge due to the application at manufacture of a hard coat protective layer. The first manufacturer to introduce this is TDK with their ‘Durabis’ coating technology.

Dell and HP have committed to begin shipment of their high end PC’s with Blu-ray by the end of 2005. Blu-ray will have built-in encryption and copy protection within the hardware and at the media manufacturing level to minimise piracy and illegal copying.

Why the need for a protective layer?

One immediate reason for the protective layer is that by packing more and more data onto the same size disc surface the recorded data can be more susceptible to playback problems caused by damage from handling, scratches and static. Also, in order to obtain the highest capacity from the Blu-ray disc format and to ensure higher precision, the recording layer in a Blu-ray disc is manufactured closer to the disc surface than both DVD and HD-DVD. This means that the Blu-ray disc has a far higher capacity than other blue laser discs such as HD-DVD, but this does mean that the disc needs to be encased in a caddy like PD and PDD or protected by an additional coating layer. By being able to manufacture a disc that can be used in its ‘naked’ form without a caddy it will ensure a more widespread use and uptake of the Blu-ray format. This is because the disc will be used in a number of different drives and consumer electronic products. Disposing of the caddy will also dramatically reduce the manufacturing and end user unit costs.

Disc Structure Comparison

With the need to have a protective coating on a ‘naked’ Blu-ray disc, TDK were the first media manufacturer to introduce a ‘scratchproof’ coating. This has been available for some time as an option on their DVD product range, but recently they have taken this technology even further with the latest version of coating technology called ‘Urbis’. The advantages of the ‘Urbis’ coating mean that discs can be used without a caddy and are far less likely to be damaged by scratches, UV light, fingerprints and dust attracted by static.

And finally….When will it all become available?

Toshiba Corp. has announced a March 2006 commercial launch date for the first HD-DVD player in the United States.

Blu-ray disc recorders were first launched in Japan in 2003. Blu-ray is available in Japan in caddy format and it is expected to be available in the US by summer 2006.

Professional Disc (PD) for broadcasting has limited availability already. It is mainly being tested and trialled in high definition TV projects by the major broadcast companies and authorities.

Professional Disc for Data (PDD), which is used for archiving and back up also has limited availability.

Both the Blu-ray group and HD-DVD group are talking together about a single format to avoid a format clash. However, as each party’s proposal appears to be that the other one drops their format, it seems unlikely it will lead to ‘peace in our time’.

Finding an affordable laptop with features you need can be as frustrating as finding a mechanic who talks about your car’s pings in a language you understand. “Just tell me what’s under the hood!” you might want to shout, because how cars work has changed. A lot. Understanding the the world of today’s computers has gotten more complex, as well. But instead of a mechanic who at least has the ability to fix your new vehicle, when it comes to laptop-shopping, you’re dependent on a salesperson who’s not about to offer information you might not even know you want. Talk of processors alone can make your head spin faster than a DVD.

One company – Toshiba – has developed a flagship line of laptops designed for every use engineers and users alike want in portable computing… The Satellite series. Currently, nine versions of this popular brand are available, all priced for affordability, without sacrificing the features users expect and need in computing. Toshiba backs its laptops with claims no other company can make: The company was the first to introduce the personal laptop in 1985; the first to offer color monitors in 1991; the first to offer laptops with a CD-ROM drive in 1995; the first to have DVD drives in 1999; and the first to offer wireless laptops in 2001.

Furthermore, Toshiba concentrates solely on laptops in the U.S.; desktop and servers aren’t available.

With pride backed by focusing on one product, Toshiba energized the laptop market with the Satellite series. Even the lowest-end Satellite has the everyday essentials you need to make the most of your time. Depending on the Satellite model you choose, you’ll enjoy the newest technology available. FM tuners, web cams, lightning-fast processors, huge storage capabilities, and even solid-state drives are available in this line. But even the lowest-end Satellites offer Toshiba‘s “Trubrite” screen technology – giving you stunning visuals, whether you’re editing family photos, or watching streaming video.

Toshiba charts the Satellite models into categories like: “Everyday Laptops,” which include the Satellites E105, A500 and M500. This group was designed for chatting with friends, viewing photos, balancing your budget and catching up with school projects – without sacrificing the power you need for essential multimedia and connectivity situations.

The Toshiba Satellite L500, the company’s most popular model, is packed with every essential you want and features you haven’t thought of but might need and will appreciate. Selected L500s contain a generous 4 GB of memory, giving you the performance you require strategizing during a favorite game – or simply helping you stay current with fast-changing software upgrades. All L500s (and many lower-end series’ models) come with Toshiba Face Recognition software, to keep you even closer to the people you talk to.

Toshiba users are quick to point out their laptops’ best features: big screens with vibrant color; better-than-expected, if not great, battery life; solid connectivity when they’re on the go, the easy-to-use touch pad, with includes options for use; and the quality of construction. As one reviewer wrote, “Despite a low price, this Satellite is not a bare-bones laptop, which you might expect. It’s a cut above any other laptop in its price range, easily, and it’s easy-to-use.”

The fact that Toshiba laptops are packed with features that don’t require extensive training, or break the bank, is something the company is happy to share. Well-made products has been Toshiba‘s mission since it produced the very first portable laptop nearly 25 years ago. The Satellite is simply the brightest offshoot of Toshiba‘s expertise, offering everyone a solid performer, at a price everyone can afford.
