[57] ABSTRACT

In the case of recording computer data, e.g., into clusters 16 to 27 of the data recording area, the range of clusters 16 to 27 is ensured as an available range in management table (parts table) of U-TOC. For example, onto parts table of No. 02h, such computer data is recorded as a segment in which cluster 16 is caused to be start address and cluster 27 is caused to be end address. For the purpose of carrying out management of recording state of computer data, FAT (File Allocation Table) is separately provided. At this table, management of recording states of clusters 16 to 27 is carried out.

Thus, computer data can be recorded onto mini-disc for recording audio data.
