SYSTEM FOR COVERTLY STORING CONTROL INFORMATION

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 of remapping information (57) indicative for translating a logical address initially mapped to a physical address to an alternate physical address in a remapping area (55), for example for defect management or logical overwrite. The device has storage means for covertly storing control data (54) while maintaining a size of the user area (53), the storage means being arranged for assigning a covert physical address to the control data and adapting the remapping information (57) to indicate that the covert physical address is not available for storing user data.
