The Specifics of Blu-ray Discs
Blu-ray currently holds the monopoly for high definition discs, although most people would not complain due to its fair price and perfect quality. With a high definition television, anybody can experience the power of Blu-ray.
The Blu-ray Disc Association is responsible for creating the Blu-ray standard. It is comprised of almost two hundred mega-corporations, all of which have a stake in Blu-ray's success. They developed the format over a period of years before completing it in 2004.
The most important thing about the Blu-ray disc is its storage capacity. The amount of data a disc can hold establishes its capabilities, so the more you have, the better. A standard Blu-ray disc can hold 25GB of data.
The storage capacity of Blu-ray discs can be increased by adding more layers to the disc itself. Each layer adds 25MB of space, and as of now, only single and dual-layer discs exist, so the maximum capacity is 50GB. In the future, as many as eight layers could be installed in each disc, meaning the maximum capacity would reach two hundred gigabytes!
The reason Blu-ray discs are so much more capable than DVDs is because of the laser they utilize. DVDs are read by a red laser, but Blu-rays are decoded through a shorter blue laser.
Blu-ray discs can be played at any speed as long as the hardware can provide that speed. The regular speed of a playing disc is thirty six megabits per second, also known as 1x. Speeds can be multiplied (2x, 3x, etc.), and technology may reach the point where the rate can reach 12x.
Blu-ray can take a number of different forms, just like the computer form of a DVD is a CD, roughly. All discs share similarities, which enables some formats to be combined, such as a proposed Blu-ray and DVD disc, which could be played on either type of respective hardware. DVD is bound to become obsolete in the near future, so many people wonder what the point of making such a format would be. - 23812
