Device and method for recording information with remapping of logical addresses to physical addresses when defects occur

Device for reading information in blocks having logical addresses on a record carrier, which device comprises

• reading means (30) for reading marks in a track on the record carrier representing the information,
• control means (20) for controlling the reading by locating each block at a physical address in the track, the control means comprising
• addressing means (31) for translating the physical addresses into the logical addresses and vice versa in dependence of defect management information, the defect management information at least including 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, and
• offset means (34) for recovering local offset information for adding an offset to a local range of physical addresses in said address translation for skipping a defect.

Method of recording of information in blocks having logical addresses located at a physical address in a track on a record carrier,

• the logical addresses corresponding to physical addresses in dependence of defect management information,
• the logical addresses constituting a contiguous storage space,
• defects being detected and the defect management information being maintained in defect management areas on the record carrier, and
• the defect management information at least including 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 method comprising
• detecting continuous recording of a series of blocks having a continuous logical address range to be recorded in a corresponding allocated physical address range,
• generating local offset information for, in the event of a defect interrupting the allocated physical address range, adding an offset to a local range of physical addresses in said address translation for skipping the defect and writing the blocks logically following the last block before the defect at physical addresses following the defect, and
• accommodating recording an end portion of at least one block of the continuous logical address range, which end portion extends beyond the allocated physical address range due to the defect.
