The Blue Ray Disc

The newest entrant in the Optical Disc Storage media market is the Blu-Ray Disc. Developed by Sony, this disc has now become the standard for HD contents. The Blu-Ray Disc has now become a popular medium for HD movies with most motion pictures studios releasing their movies on the BD-ROM.

Toshiba was developing the HD DVD to supersede the DVD while Sony was busy with the Blu-Ray. Warner Bros, one of the major motion pictures studio, had supported the HD DVD during the initial phases and the market share of the HD DVD had been much more compared to the BD-ROM. However, Sony’s Play Station 3 helped popularize BD-ROM and in February 2008 Toshiba withdrew its support for HD DVD.

The basic difference between a BD-ROM and a DVD-ROM is that the latter uses a 650 nm red laser, the former uses a 405 nm blue-violet laser. This enables the BD-ROM to pack about six times the data as the DVD. The standard BD-ROM capacity is 25 GB while that of a Dual Layer BD-ROM is 50 GB.

Google Chrome OS

Google introduced its web browser application, Google Chrome which faced stiff competition from the already established applications like the Internet Explorer and Mozilla’s Firefox. Even though it was new, because of its user friendly interface it gained recognition and got positive responses. Now, Google have announced its new operating system, though the release date is still sketchy, it is due to release sometime in 2010.

Google Chrome OS is an open source and a lightweight operating system which will initially be targeted only for netbooks. Google Chrome OS will be available for consumers in the latter half of 2010. The OS as told by Google should be extremely light and fast, allowing the users an extremely quick start up and onto the web in a few seconds. The user interface is minimal to stay out of the way, and most of the user experience takes place on the web. As was done for the Google Chrome browser, Google is going back to the basics and completely redesigning the underlying security architecture of the OS so that users don’t have to deal with viruses, malware and security updates

Play Station 3 Slim

The Sony Play Station, the third console from the Play Station series was released amidst much fanfare and lived up to its hype and was a hit amongst the fans of the play station series. The play station was also the first Blu ray 2.0 compliant player in the market. Facing stiff competition from the Microsoft Xbox 360 and the Nintendo Wii, there were rumors that Sony was releasing the PS3 slim, hype being generated more so because the same happened in the case of the Play station 2, where in a slim model was introduced.

Sony laid all rumors to rest when it launched the Sony play station 3 slim in September 2009 with a capacity of a 120 GB. Apart from being smaller in size and lighter than the earlier model, the slim model also consumes less power and has a better cooling system as it utilizes the 45nm cell. One more noticeable difference is the PS3 slim has a matt finish rather than the usual glossy finish which was adorned in the earlier model.

Blue Ray Disc

When the DVD gained commercial acceptance, users were awed with its storage capacity of 4.7 GB which was a huge jump from the 700 MB of space which was provided by the CD. Now, there is a newer technology concerning optical disc storage which is shaping up in the form of Blu Ray Disc, though still not a mainstream option, they are attracting a lot of attention because of the capacity they have to offer, 25 GB for a single layer Blu ray Disc and 50 G for a dual layer disc. This capacity is achieved even though; the physical dimensions are same to that of the standard CD’s and DVD’s.

The Blu Ray Discs are being jointly developed by the Blu Ray Disc Association and a number of other manufacturers including Sony, Apple and Dell. These discs use a blue laser to read-write data instead of the red laser which is used in DVD’s, hence the name.

LED TV – More style than substance

The latest buzz in the Television world is “LED TV”. Even the laptops, nowadays, are coming with LED screens. So what is this LED screen that has the consumer world abuzz? Frankly, it is more of an advertising gimmick than anything else. The basic technology still remains LCD, only that the backlighting is done with the help of LEDs as opposed to Cold Cathode Fluorescent Lights (CCFL).

An LED backlighting can produce better dynamic contrast, when RGB LEDS are used, than CCFL and make for compact screens. However most screens use edge-LED that only offers compactness. Use of edge-LED is used to produce really thin screens and this technology is quite useful especially for laptops. One more advantage that LED-LCDs have over CCFL-LCDs is that they consume lesser power.

The first RGB LED-LCD to be produced was Sony Qualia 005 in 2004. However it was Samsung that really popularized this technology.
