摘要:
A device for recording records blocks of information on logical addresses on a record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses in dependence on defect management information that includes defect information on a defective status of physical addresses and remapping information on translating a logical address initially mapped to an initial physical address to an alternate physical address. The device has a real-time storage unit for writing real-time information blocks (77) to respective initial physical addresses irrespective of the defective status. When recording at a defective status location (76), the real-time information block is temporarily stored in a memory (80). In a separate period, when the writing of real-time information blocks is suspended, said temporarily stored real-time information blocks are additionally written to alternate physical addresses (81). The defect management information (73) is updated to indicate that the real-time information block is present at both locations.
