ABSTRACT:
On a CD-R, a UID that is unique identification information is pre-recorded. When the CD-R is loaded into an information terminal unit, the UID is read and transmitted to a management server through the Internet. The management server determines whether predetermined data can be recorded onto the CD-R in accordance with the received UID. For example, when the UID is valid, contents data is downloaded from the management server to the information terminal unit and recorded onto the CD-R. 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 to the information terminal unit. As a result, contents data recorded on another recording medium can be copied or moved to the CD-R.
