Abstract
Provided is a recording/reproduction apparatus capable of securing a backup area for management information on a recording medium without affecting the capacity of a user data area. Before a hard disk drive or a disc medium (recording medium) is finalized, metadata is recorded in a metadata area and when the hard disk drive or the disc medium are finalized, a user data area portion corresponding to the volume of metadata required for the finalizing is set as a metadata mirror area and then the metadata recorded in the metadata area is copied to the metadata mirror area.
