On a CD-R 1, a UID that is unique identification information is pre-recorded. When the CD-R 1 is loaded into an information terminal unit 10, the UID is read and transmitted to a management server 12 through Internet 11. The management server 12 determines whether or not predetermine data can be recorded onto the CD-R 1 in accordance with the received UID. For example, when the UID is valid, contents data is downloaded from the management server 12 to the information terminal unit 10 and recorded onto the CD-R 1. In addition, for example, when the UID is valid, a notification that represents that contents data is permitted to be copied or moved is transmitted from the management server 12 to the information terminal unit 10. As a result, contents data recorded on another recording medium can be copied or moved to the CD-R 1.
