Philips Electronics unveiled an optical disk drive on Monday for use in computers that can burn and play CDs and DVDs in three formats, including the new Blu-ray standard.
The drive, to be presented at the Consumer Electronics Show in Las Vegas this week and to be available in the second half of 2005, comes as electronics giants jockey for support of their new DVD systems.
Many film studios had expected that Blue-ray would not hit the market until 2006.
This level of storage allows film publishers to put a full-length movie in the high-definition format on one disc.
