"The PD/CD-ROM Library is a natural extension of last year's PD drive, a single drive that allows a user to read CD-ROM titles at quad-speed, and, in the same drive, insert and read/write a 650 MB PD disc," said Timothy J.
Networked computer users can share CD-ROMs stored in the PD/CD-ROM Library as well as write their own data to a rewritable 650 MB PD disc. Once written and stored in the library's disc tower, a PD disc can be quickly retrieved and shared by others on a network.
chains such as Wal-Mart, Target, Best Buy and Circuit City buy millions of PD discs each month, while many DVD companies around the world are releasing these titles in their budget lines.
