摘要:
An information recording medium (1) includes a disk information area (4); a user area (6) including a plurality of sectors; and a spare area (7) 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 (7) is located radially inward from the user area (6). 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 (7), is recorded in the disk information area (4).
摘要:
An information recording medium including a plurality of sectors of the present invention includes: a first spare area including a spare sector for replacing a defective sector among the plurality of sectors; a defect management information area for managing the replacement of the defective sector by the spare sector; and a volume space in which user data can be recorded. The volume space is configured so that a second spare area including a spare sector for replacing a defective sector among the plurality of sectors can be additionally allocated. Location information indicating a location of the second spare area is recorded in the defect management information area.
摘要:
An information recording medium comprises a data recording area (102). A lead-in area (108) and a volume space (104) are allocated in the data recording area in advance. The volume space is constructed so as to allow a logical zone (114,116) for recording at least a volume-file structure (118) and an overrun protection area (110,112) for preventing an access to an unrecorded area (138) to be alternately allocated in the volume space. The lead-in area and the over-run protection area each include a chain volume management information area (132,134,136) for storing chain volume management information. The chain volume management information includes address information (140,144) of a subsequent logical zone and address information (142,146) of a subsequent chain volume management information area.
摘要:
An information recording disc having a burst cutting area (BCA) (102) for recording control information for a reproducing apparatus by removing a reflective layer of the disc in a striped shape and a data recording area (104) for recording user data, wherein the burst cutting area (102) includes at least one BCA control information area and the BCA control information area comprises: an application identifier area (106) for identifying applications of control data; a data length area (108) for indicating data length of the control data; and an application specific data area (109) for recording the control data.
摘要:
An information recording medium comprises a user area, and a spare area including a replacement area, wherein the replacement area may be used instead of a defective area in the user area. The user area and the spare area include a plurality of sectors. Each of the plurality of sectors includes a user data area for recording user data, and an attribute data area for recording defect replacement allowance attribute data. The defect replacement allowance attribute data indicates whether recording of the user data has been executed in a state that the execution of a defect replacement process is allowed. In the defect replacement process, the defective area in the user area is replaced with the replacement area in the spare area.
