Parsons said next-generation DVDs must offer much more storage than today's 5GB to 9GB. HD DVD, backed primarily by Toshiba, NEC and a number of studios--including Paramount Home Entertainment, Universal Pictures, Warner Brothers and New Line Cinema--is capable of storing 15GB of data on a single-layer disc. A Blu-ray DVD can store up to 25GB on a single layer and 50GB on a dual-layer disc. Both formats use blue lasers rather than the regular red one.
