Abstract
The apparatus controls access to the contents. The apparatus comprises MO device, MPEG2 decoder, and MO media as physical elements. Information for identifying these physical elements (identifying information) is allocated to each of these physical elements. License information, indicating whether access to the contents is to be allowed or not, is recorded on a MO media. Access to the contents recorded on the MO media is controlled based on the license information and the identifying information.
