The RS08 is a fixed-platter fixed-head disk drive that can store up to 262KW of data. It used 128 fixed read/write heads, 2048 words/track, and recorded data on a single nickel-cobalt plated surface. The data transfer rate was 62.5K words per second (operating on 60 Hz power), or 52.083 words per second (on 50 Hz power).
Its controller is the RF08 disk controller.
