Japanese group works on new high-capacity DVD

A coalition of Japanese firms and universities plans to develop an optical disc that can store 1.5 terabytes, the equivalent of about 300 DVDs, a report said yesterday.

The optical disc would be able to record 300 two-hour films and the player to use it would be compatible with standard DVDs, the Nihon Keizai Shimbun reported.

Japanese electronics giant Matsushita Electric Industrial Co, office equipment maker Ricoh Co and Osaka University will start developing the optical disc with plans to have it on the market by 2010.

Audio-visual equipment maker Pioneer Corp, Mitsubishi Chemical Corp, Aishin Seiki Co, Kyushu University and Shizuoka University will also be involved.

The coalition will invest Japanese Yen 2 billion to Japanese Yen 3 billion (US$16.6 million to US$24.9 million) over five years, starting April, to develop the disc.

The disc, 12cm in diameter, will introduce 3D multilayer optical memory technology and storing data in a 10-layer structure, according to the newspaper report.
