About Blu-ray
Blu-ray, also known as Blu-ray Disc (BD) is the name of a new developing
optical disc format.The Blu-ray format is intended to enable broader
recording, rewriting and playback of high-definition video (HD), as
well as provide an improved placement system for storing large amounts of data.
The Blu-ray format utilizes a blue-violet laser to read and write data, while current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data.
Despite the different type of lasers used, it is claimed
that Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit.
The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm).
This difference in wavelength makes it possible to focus the
blue-violet laser with pin-point precision that's much greater
than that of a red laser.
This type of pin-point accuracy also allows data to be packed more tightly and stored in less
space, so it's possible to fit more data on a disc the same size as
is present on today's CD/DVD.
Blu-ray technology offers more than five times the storage capacity of traditional
DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.
The Blu-ray name is a derived combination of "Blue" (blue-violet laser) and "Ray" (optical ray).
The Blu-ray Disc format was developed by the Blu-ray Disc Association (BDA).
Apple Computer,
