摘要: An assembly added to a conventional VHS cassette provides a wheel 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 to carry an erase head against the tape, or locking the cassette brakes in the engaged position once the cassette is removed form the tape deck.
