Abstract
The rewriting counts in respective areas of a rewritable medium are uniformized. If empty areas are present on the rewritable medium rearward of a recording start position in terms of addresses, then data is recorded in those empty areas. When no empty areas become available rearward of the recording start position, data is then recorded in empty areas forward of the recording start position. The numbers of times that data is recorded in recording areas of the recording medium are thus averaged.
