Abstract:
A device for recording information records blocks having continuous logical addresses on a record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses in dependence of defect management information, which includes remapping information indicative for translating a logical address initially mapped to a physical address exhibiting a defect to an alternate physical address in a defect management area. The device has a continuous data detection unit for detecting a logically continuous data, and a defect management reorganizing unit. The physical addresses of remapped logical addresses in the logically continuous data are determined, and the defect management information is reorganized by remapping at least one of the remapped logical addresses to a different defect management area. During read-out the remapped logical addresses in the logically continuous address range are retrieved from a single defect management area.
