Bluray Explained

By Brian Reynard


New technology is now giving the chance for viewers to record and store high definition programming onto DVDs. Blu-ray Disc is one method of recording HD content onto an optical disc. A blue-laser optical disc (MPEG-2 or MPEG-4) is used. Systems that use this technology will be well placed to play traditional DVDs, but the point of Blu-ray is to create an image that's as near to the HD format as practicable. The name Blu-ray comes from the blue laser that decodes and copies info to each disk.

Blu-ray technology may actually revolutionize the arena of high definition programming, and even the wedding video industry. The Blu-ray disk format offers greater potential for storage, customarily 25 gigabytes, which exceeds that of the standard DVD (15 gbs.). One single-layer Blu-ray disk can hold about 4 hours of high definition content. A two-layer disk can contain 8 hours of HD content. Four- and eight-layer disks are now in the works. These disks would have storage capacities of 100 and 200 gigabytes. The Blu-ray recording system employs a shorter wavelength for recording information than standard CDs and DVDs, and this is an element of what allows it to hold more content on a single disk.

Blu-ray in addition has influenced the PC industry, particularly in terms of data storage capability. Numerous major firms have come out in support of Blu-ray, including Apple, Dell, Hitachi, Lead runner, and Sony. Hewlett Packard plans to market desktop PCs and PCs that utilise Blu-ray technology. Sony has declared that it will introduce a Blu-ray component in PlayStation 3, which is expected to appear in November of the present year. Microsoft has also asserted that it may add a Blu-ray part to its Xbox 360. Now, Blu-ray is available only in Japan, but it will appear in the United States in May, in computer console games and a DVD system that recreates a high definition effect on a viewer's TV.

Many motion picture studios have Blu-ray films planned for future release. In 2005, Sony Photographs cornered the market on the 1st Blu-ray feature-length movie disk, which was Charlie's Angels: Full Throttle. Studios that support the technology include Walt Disney and Twentieth Century Fox.

Competing with Blu-ray in the area of HD storage is HD DVD. HD DVD disks have less storage capability, but they're less expensive to supply. Other big-name corporations are showing their support for this option, including Microsoft, Intel and Toshiba, as well as Universal Studios. In what may be the smartest move, some companies are backing both types of technology, making sure that their products support both Blu-ray and HD DVD. These corporations include Samsung, Paramount and Warner Brothers.

Blu-ray is facing challenges from other competitors in the HD market: the Enhanced Flexible disk, the Digital Multilayer disk, and the Holographic Versatile disk are a few alternatives to Blu-ray. But at the moment, Blu-ray has a strong lead in the HD race.
