Hitachi has developed a technology which allows up to 400 hours of DVD-quality video on a single DVD disc. The capacity is achieved by using more than two layers to store the data. Current DVD specifications allow a maximum of two layers per side, and two sides per disc. That adds up to around eight hours of video at a decent bitrate.
Hitachi hopes to make the technology commercially available by 2007. I'm sure there will still be demand for a 900 GB optical disc then, even with the release of the blue-laser formats.
