This standard is named Blu-ray, because it uses a blue laser instead of a red one, which is at the moment used for DVD reading and recording. Blu-ray is designed to store 25GB on a single-layered dics.
It is aimed at recording and storing high-definition video which studios, video renters and retailers see as a major growth opportunity for the home video market in coming years.Players, computer drives and software compatible with the Blu-ray format are expected by the end of 2005. Microsoft stated last month that their next-gen Windows OS, Longhorn, would be compatible with HD DVD. But they didn't say whether it would support Blu-ray or not.
The founders' group has 13 members comprising the leading names in consumer electronics and computing, among them Sony Corp., Philips, Thomson, Dell Inc. and Hewlett-Packard Co.
The Blu-ray format those companies are backing is expected to compete with another blue-laser standard, HD DVD, backed by NEC Corp. and Toshiba Corp.
