摘要： An additionally recordable information recording medium has a complicated management structure for managing an unrecorded area. Therefore, there are problems that it takes a long time for a disk to startup and it is difficult to build a recording/reproducing system. The additionally recordable information recording medium according to the present invention includes a simple data structure for managing a location information for a recorded area located at the rearmost location in a user data area. An additionally recordable apparatus according to the present invention also includes means for updating the location information of the recorded area so that the recorded area located at the rearmost location in the user data area is always managed.

摘要： An information recording apparatus 110 includes a defect list update section 122 for updating a defect list having a defect address registered therein which represents a position of a defect area existing in a user area, and a recording section 113 for recording information on the information recording medium 130 based on the updated defect list. The defect list update section 122 determines whether or not an area designated by the defect address registered in the defect list is a defect area; and when the area designated by the defect address is determined not to be a defect area, the defect list update section 122 deletes the defect address, registered in the defect list, from the defect list.

摘要： An information recording medium includes a disk information area; a user area including a plurality of sectors; and a spare area including at least one sector which, when at least one of the plurality of sectors included in the user area is a defective sector, is usable instead of the at least one defective sector. The spare area is located radially inward from the user area. A physical sector number of a sector to which a logical sector number “0” is assigned, among the plurality of sectors included in the user area and the at least one sector included in the spare area, is recorded in the disk information area.
