Learning About the Blu-ray Disc
With the advent of high definition televisions, people like to make the most of their expensive pieces of technology. The Blu-ray disc makes that possible, since it plays graphics and sounds in stunning, crystal clear HD.
The Blu-ray disc, abbreviated BD, was developed by the Blu-ray Disc Association. This conglomerate has members from many different electronics sectors; 180 to be specific. It was formed in the early 2000s and exists today to manage Blu-ray operations.
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.
Interestingly, 25GB is the lowest end of the Blu-ray spectrum. When extra layers are added, the storage capacity increases in increments of 25MB. For example, a two-layer disc can hold 50GB of data.
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.
The current standard speed for Blu-ray discs is known as 1x. As movies become more defined, rates can be increased to 10x or 12x, but that is difficult to reach due to limitations in hardware.
Blu-ray and DVD are two separate things, but there may be a way to combine them in a Blu-ray/DVD disc. That way, those who didn't have a Blu-ray or DVD player could still watch the movie. However, since DVD will eventually become obsolete any way, there may be no great purpose in pursuing this. - 23806
