TOKYO, Aug 03, 2004 (Kyodo via COMTEX) -- The world's 13 major electronics makers said Tuesday they will draw up by Sept. 30 a set of technological specifications for ultra-large-memory prerecorded "Blu-ray Disc" videodisks whose functions will be limited to playing back contents.
This type of Blu-ray Disc video storage medium will carry such content as movies. The Blu-ray Disc technology combines optical disk and blue-laser technologies.
Another type of Blu-ray Disc that allows users to both record and play back video images has already been put on the market.
The 13 include Sony Corp., Matsushita Electric Industrial Co. and Dell Inc. of the United States.
These manufacturers plan to start marketing, by the end of fiscal 2005, video software as well as the Blu-ray Disc players whose functions will be limited to playing back prerecorded contents, they said.
In a related move, Sony officials said the company will equip an upcoming version of the PlayStation2 video console with a Blu-ray Disc player, so that purchasers can enjoy both video games and movies of high-image quality.
Sony plans to announce the outline of the next version of PlayStation2 by March 31, 2005, they said.
Sony's Blu-ray Disc provides 23 gigabyte storage memory capacity -- five times that of a DVD.
Compared with CD or DVD systems based on red lasers, Blu-ray machines use blue lasers that have a shorter wavelength and require much less space to store each bit of information.
