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,  Dell Inc,  Phillips, Samsung, Sharp Corporation, Sony Corporation, Sun Microsystems,  TDK Corporation, Twentieth Century Fox, Walt Disney Pictures, Warner Bros Entertainment represent but a few of the  member companies that compose the BDA.
