Abstract
A recording medium includes a nonvolatile memory having a storage region used for writing of data, and a controller configured to control the writing of data onto the storage region. The controller divides the storage region into a plurality of areas, selects one area among the plurality of areas, and uses only the one area as a data recording region. When a rewriting ratio in the one area reaches a first predetermined value, the controller switches the data recording region from the one area to another area having not yet used among the plurality of areas.
