...Sony also announced that a Blu-ray Disc aftermarket drive for personal computers is also expected to be available this year, and will support 25GB/50GB BD-R/RE discs, as well as DVD+R/+RW, and CD-R/RW recordable media. This drive will be bundled with consumer-level BD recording software and accessories for creation of High-Definition home video and data Blu-ray Discs.

Beginning in the spring, Sony will begin selling a 25GB single layer BD-R and the BD-RE recording media. Dual layer 50GB capacity recordable media will follow in the subsequent months. Recordable Blu-ray Discs utilize Sony's AccuCORE technology offering superb archival and reliability, scratch guard protection and temperature durability.
