A group promoting and developing a format for a next-generation DVD technology announced on Wednesday the completion of the first version of the specification, paving the way for disk production.
The Blu-ray Disc Founders group said the physical format for the read-only version of Blu-ray Discs is complete, so manufacturers can begin preparing to produce disks. Players and discs are not expected to be available until late 2005. Other aspects of the read-only version, such as which codecs to support, have to be determined. Rewritable Blu-ray Discs and recorders are already available in Japan from Panasonic and Sony. Blu-ray Disc, and rival format HD-DVD, are considered next-generation DVD technologies and are based on blue lasers. Current DVD technology is based on red lasers. The blue-laser technology will allow greater storage capacities, up to 50GB for dual-layer rewritable disks, compared with 4.7GB on current DVDs.

    Do HD-DVD and Blu-Ray have different capacities, or what? Or are they just differnet companies trying to gain control over the market?

    Blu-Ray uses blue lasers and holds like 10 more gigs than an HD-DVD, unfortunately it has no back compatibility with old DVDs.

    Ah, ok. They both use blue lasers apparently. And what do you mean by "back compatibility with old DVDs"? Do you mean DVD players, or what?
