摘要： This invention relates to a recording medium management method, and digital data for computer processing are stored on a magnetooptic disk that is usually used to record compressed digital audio data. When computer data are recorded to clusters (16-27) of a data recording area, the range of the clusters (16-27) is secured as a usable range in a management table (parts table) of U-TOC. On the parts table (02h), a segment using is recorded using the cluster (16) as a start address and the cluster (27) as an end address. To manage the recording state of the computer data, FAT (File Allocation Table) is separately prepared to manage the recording state of the clusters (16-27).
