Abstract:
In a recording medium including stacked recording layers, management data requiring reliability is recorded in the recording layer far from the surface of the recording medium and data bodies are recorded in the recording layer close to the surface of the recording medium. Thus a data file can be read even if defects such as fingerprints and scratches occur on the surface of the recording medium.
