TOKYO, Feb. 20 -- Nine companies have jointly established the basic specifications for a next-generation large-capacity optical disc video recording format called "Blu-ray Disc." The Blu-ray Disc enables the recording, rewriting and play back of up to 27 gigabytes of data on a single-sided single layer, 12-cm CD/DVD-size disc using a 405-nm blue-violet laser. The companies that established the basic specifications for the Blu-ray Disc are: Hitachi Ltd., LG Electronics Inc., Matsushita Electric Industrial Co. Ltd., Pioneer Corp., Royal Philips Electronics, Samsung Electronics Co.
