Abstract:
1. An optical disk apparatus comprising: a receiving unit for receiving TV broadcast signals and acquiring data from the TV broadcast signals; a recording/reading unit for irradiating a laser beam onto an optical disk, recording the data acquired by the receiving unit to the optical disk, and reading recorded information from the optical disk; a storage unit for storing one or more pre-registered account names; an operation unit including a control unit which judges whether the account name is already recorded to the optical disk when the account name recording operation is selected by the account register key, and which instructs the recording/reading unit to record the account name of the user to the optical disk when judging that the account name is not recorded to the optical disk, wherein the control unit judges whether the account name recorded to the optical disk matches the single account name selected by the select key when recording of the data acquired by the receiving unit to the optical disk is instructed, and permits the recording/reading unit to record the data to the optical disk if it is judged that the account names match, and prohibits the recording/reading unit from recording the data to the optical disk if it is judged that the account names do not match.
