发明名称 LIMITED PLAY TAPE CASSETTE SYSTEM
摘要 An assembly added to e.g. a conventional VHS cassette provides a wheel (22) for counting the number of plays, or replays of segments of more than a predetermined length, and preventing further replay after the last authorized play by either releasing a spring biased arm (41) to carry an erase head (36) against the tape, or locking the cassette brakes in the engaged position once the cassette is removed from the tape deck.
