The method and apparatus can register defective areas in a recording medium not having a dedicated sparing area. A data recording area and a sparing area are not preliminarily divided. When a defective area is found, data is transferred to another area in the recording area, and the defective area is registered as being in a recorded state in a table for managing the recorded state in each of the recording areas.
