摘要:
A device for recording records information in blocks having logical addresses at a physical address in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information, such as primary and secondary defect lists and remapping tables, maintained in defect management areas (61). The defect management information includes assignment information indicative of assignment of physical addresses in parts of the track to user data areas or to defect management areas. The device has assignment means for dynamically adapting the assignment information in dependence of detected defects (54) by assigning an additional physical address range to an additional defect management area (61). The additional physical address range starts near the detected defect (54). Hence the defect (54) is covered by a defect management area, which reduces the need for remapping.
