CHIBA, JAPAN -- Sanyo Electric unveiled a prototype player supporting the next-generation optical disc format HD-DVD at the Ceatec 2004 show here this week.
The company's HD-DVD player was on show alongside a prototype from Toshiba, which has been seen at other events. No additional details of either machine were available, although the presence of a Sanyo player at the show points toward a start to HD-DVD development at Sanyo before the company announced its support for the format on August 31.
HD-DVD was developed under the auspices of the DVD Forum and draws heavily on technology from both Toshiba and NEC. Major Japanese optical disc-maker Memory-Tech has also been involved in disc production technology. The format uses a blue laser to enable storage of several times more data than a conventional DVD on an equivalent size disc.
A group of other companies, led by Sony and Matsushita Electric Industrial (Panasonic), has proposed and developed a rival format called Blu-ray Disc.
On Display
The new Sanyo player and Toshiba prototype were on show in a joint HD-DVD promotion booth that also had on display several sample discs made by a number of companies, including Memory-Tech, Ritek, Prodisc Technology, Mitsubishi Kagaku Media, Hitachi Maxell, Imation, Cinram International, and Advanced Media.
The discs included single-sided and double-sided ROM discs, or 15GB and 30GB capacity, and single-layer HD-DVD-R discs of 20GB capacity. All of the discs were genuine samples, as opposed to other optical discs with HD-DVD labels, and all the companies were preparing for mass production, a Toshiba spokesperson says.
Toshiba and NEC have promised to commercialize HD-DVD during 2005. The first commercial Blu-ray Disc machines are already on the market in Japan, although sales have been limited by a high price tag and an inability to play back prerecorded content.
