It is a disc data storage medium just like CD or DVD but with higher data storage capacities of upto 50GB. It was developed by the Blu-ray Disc Association and Sony was the main creator of blu-ray disc. It uses a 405 nm blue-violet laser and so its name is blu-ray. It is the latest technology built especially for high-definition audio and video at high resolutions and screen rate. more information at http://en.wikipedia.org/wiki/Blu-ray_Disc

New format for Optical storage media whcih can store up to 25MB of data ( single layered) or 50 MB for dual layer disks. For Movies Blue Ray caters to 7.1 Channel 192 Khz / 24 bit sampled audio data either in Dolby TrueHD or DTS MA lossless audio format in addition to DVD audio ( 5.1 ) and AC97 Audio ( Sterio) for backward compatibility.

Blu-ray Disc is an optical disc storage medium to supersede the standard DVD format. Its main uses are for storing PlayStation 3 games, high-definition video and data storage with up to 50GB per disc. The disc has the same physical dimensions as standard DVDs and CDs. The name Blu-ray Disc derives from the blue-violet laser used to read the disc. While a standard DVD uses a 650 nanometre red laser, Blu-ray uses a shorter wavelength, a 405 nm blue-violet laser, and allows for almost six times more data storage than on a DVD.
