  • Patent number: 4581671
    Abstract: A magnetic tape recording and playback system having a tape cassette and battery pack joined by a frangible connection in an integral assembly, wherein for recording the assembly provides battery power to the recorder and the recorder provides recording signals to the cassette, and for playback, the battery is broken away from the cassette and discarded and the cassette is inserted into the playback unit, which can accept only the cassette without the battery. This prevents re-use of the cassette in the recorder and assures the use of a fresh battery for each recording session.
