INFORMATION RECORDING REPRODUCER

摘要

Data management information (162) is information for managing the right to use content data stored in a data storage section (15) and is managed for each user. Specifically, the data management information (162) is a title list of each user. When the right to use the content data stored in the data storage section (15) is present, the data management information associates the user with the recorded content data and applies a unique link name to the association for management. A system control unit of an information recording reproducer controls sharing of the content data according to the data management information (162).
