Abstract
It is required for multimedia optical disks to possess a storage capacity of more than that of CD-ROMs (540 MBytes), the capability of overwrite operation, and a data transfer rate required in the MPEG2 standard, because a variety of data, such as text data, graphic data, and digital video signals, are expected to be dealt with in a unified manner. The common specifications of 90 mm phase-change optical disk(1) were developed by the Phase-Change Optical Disk Workshop (29 volunteer members, Japan) to satisfy these requirements. Optical disks based on these specifications have a high performance with a capacity of 600 MBytes per both sides and a data transfer rate of 9 Mbps, in spite of their size smaller than CD-ROMs. This paper describes an outline of the common specifications and the results of basic performance tests on the optical disks based on the common specifications provided by 9 manufacturers.
