Summary :

A new 90-mm magneto-optical disk subsystem has been developed. It features a rewritable 100-Mbyte disk, a half-height drive and a highly reliable controller. Its effective data transfer rate is 330 kbytes/second, its average access time is 100 ms, and its data error rate is less than 10^-12 events/bit. This subsystem uses a novel design method based on the media's physical characteristics. This method employs a statistical model to describe error occurrences. It considers the dimensional characteristics of media defects by analyzing the reproduced signal. Using this design method, the error control strategy, which consists of a defect management scheme and an error-correcting procedure, is determined. Furthermore, this subsystem uses a new physical media format called Discrete Block Format. Optical read-only madia compatibility can be obtained quite easily with this format. The subsystem can be used with personal computers, communication terminals and measuring instruments.
