Abstract:
An MIA containing file-system information is updated and a recording/reproduction block 53 records Main MIA containing the updated information in block B″1 in a free area on a recording medium. In addition, Main G1, Res.G1, Main G2, Res.G2 and G3, which form a group of files each serving as an object of group management, are recorded in block B″2. Furthermore, Res.MIA containing a backup of the file-system information is recorded in block B″3. By recording information in this way, the recording area of the recording medium can be used effectively. The present invention can be applied to an information-recording/reproduction apparatus for recording information serving as an object of the group management on the recording medium.
