Abstract
A recording device performs recording on a recording medium such as a DVD, and playback compatibility of the recording medium is increased. In circumstances such as when a standard is established after the manufacture of a playback apparatus, there are playback devices that physically cannot read information for decrypting encrypted data from a predetermined area of the recording medium due to the specifications of the playback apparatus, and therefore the playback apparatus cannot use the recording medium. In order for the recording medium to be able to be used in such a playback apparatus, the recording device reads data recorded in the predetermined area of the recording medium, and records the read data in another area that is readable by the playback apparatus.
