Abstract
Abstract A system for protecting an unauthorized use of a recorded content. The system uses a recording medium including a first recording area in which data including a program are recorded and further including a second recording area which is formed at a specific position thereof and in which data including a specific identification code are recorded so as not to be rewritable by a user. The recording medium is coupled through a recording/reproduction device to a control unit for executing the program recorded in the first recording area of the recording medium. The control unit reads out the identification code recorded in the second recording area and stops the execution of the program when the read-out identification code is not coincident with a predetermined ID code.
