摘要
A recorder provides to a recorder/player via a high-speed bus content-related information such as a digital audio signal as information, a content ID being identification information on the digital audio signal and a standard playing time of the digital audio signal. The recorder/player has a controller which stores the content ID into a copy-history information management memory when the same content ID is not existent in the memory. The content ID is held for a period measured by a timer. For this period, the recording function of the recorder/player is limited so that the same digital audio signal cannot be copied at a high speed.
