Zusammenfassung:	PROBLEM TO BE SOLVED: To realize defective sector management which does not require a large capacity for an alternative area reserved for replacing a defective sector and which never degrades access performance to an area having defective sector even when many defective sectors occur locally. SOLUTION: When a processor 350 detects high-density defective sectors (640-1), the processor 350 assigns an unused cluster 550 in a file data area and a sector 570 which can be normally accessed in the cluster replaced with the unused cluster as the alternative area to the defective sectors 70-1.
