Information storage medium, method of managing replacement information, recording/reproducing apparatus, and host apparatus

摘要

An information storage medium, a replacement information management method, a recording/reproducing apparatus, and a host apparatus are provided. The information storage medium includes: a defect list for storing replacement entries having replacement information related to replacement of defects detected in data recorded on the medium or replacement to update data recorded on the medium, wherein at least one replacement entry having invalid replacement information among the replacement entries stored in the defect list is deleted. Accordingly, an overflow of the defect list can be prevented and the size of the defect list can be minimized, thereby increasing medium usage efficiency.
