Abstract
A DVD recorder is provided in which access control is effected by a driver layer (), a UDF file system layer (,) that reads and writes data from and to a DVD-RW with reference to a file system, and a data base layer () that accesses the UDF file system layer () with reference to content management information for management of contents stored in the DVD-RW. The data base layer () reads TMP_VMGI which is intermediate-state management information for the DVD-RW, and provisionally registers a file system into the UDF file system layer () with reference to information included in the TMP_VMGI. Thus, a file system is provisionally formed even if the DVD-RW loaded in the DVD recorder is in the intermediate state having no file system recorded therein.
