Nine leading companies announced that they have jointly established the basic specs for a next-generation, large-capacity, optical-disc video-recording format called “Blue-Ray Disc.” The disc enables the recording, rewriting and playback of up to 27 GB of data on a single-sided, single-layer, 12cm CD/DVD-sized disc using a 405nm blue-violet laser. The disc can also record over two hours of digital high-definition video and more than 13 hours of standard TV broadcasting. The companies involved include Hitachi, LG Electronics, Matsushita Electric Industrial Co., Pioneer, Royal Philips Electronics, Samsung Electronics, Sharp Corporation, Sony Corporation and Thomson Multimedia. These companies plan on licensing the new format as soon as the specs are completed, which is expected around spring 2002.

Blue-Ray Disc's main specifications include: 23.3/25/27GB recording capacity, 36Mbps high-speed data-transfer rate, phase-change recording format, MPEG-2 video-recording format, and AC3 and MPEG-1, Layer 2 audio-recording format.
