<p>A drive device (310) includes a recording/reproducing unit (314) and a drive control unit (311). The drive control device (311) decides whether alternative management information including alternative source physical address coinciding with the physical address corresponding to the logical address contained in the recording instruction is found in the alternative management information list (S301). If no alternative management information is found, the drive control unit (311) executes processing as a first pseudo-overwrite recording at the position indicated by the physical address corresponding to the logical address contained in the recording instruction (S302, S303). If alternative management information is found, the drive control unit (311) executes processing as the second pseudo-overwrite recording or after at the position indicated by the physical address corresponding to the logical address contained in the recording instruction (S304, S305).</p> |
