IMPROVED DEFECT LIST, METHOD FOR RECOGNIZING DISK AND DEFECT SECTOR LOCATION AND METHOD FOR MANAGING DEFECT

摘要

PURPOSE: A detect managing method is provided to reduce a capacity for a detect management of a driver by expressing location information of a detect sector in a detect block in a bit map form. CONSTITUTION: In a method for performing a disk detect management, in case where the number of detective blocks is less than that capable of being managed by a defect block table, the defect block table is recorded to a defect management region so as to perform a detect management. In case where the number of detective blocks is more than that capable of being managed by a defect block table, the defect block bit map is recorded to the defect management region so as to perform the detect management.
