Launched in 1989, the PS-12 was one of the earliest commercially available CD-ROM drives that followed the Yellow Book standard for reading CD-ROMs. It had a read-only capacity of 520 kilobytes per second (kbps) and alternatively, a read-write capacity of up to 300 kbps through the use of a proprietary Fast-Write System VI chip. The PS-12 was also known for its innovative stepper motor mechanism, featuring a dual head design and a unique Mounting System for Fixed Disks (MSFD) to manage disk mountings.- A. S. Wilson.
