ABSTRACT:
A format operation control device performs a simple format operation and a standard format operation for a recording medium having a control data area, storing file control information, and a record data area, storing record data. The control data area and the record data area have sectors. In the simple format operation, the control data area is initialized and bad sectors are not detected from each of the sectors of the recording medium. The standard format operation includes a substitution process and a bad sector mapping. In the substitution process, the control data area is initialized, bad sectors are detected from each of the sectors of the recording medium, and a physical format is performed so that good sectors are used instead of bad sectors. In a bad sector mapping, the control data area is initialized, bad sectors are detected from the record data area, and a bad mark is recorded in the FAT-table corresponding to the cluster containing the bad sector.
