  • Patent number: 6381400
    Abstract: A method for controlling the speed of a capstan motor in a video cassette recorder (VCR) includes modulating a capstan frequency generating (CFG) signal into a pulse signal. Time intervals corresponding to one of a rising edge to a next rising edge and a falling edge to a next falling edge of the pulse signal are calculated. The calculated time intervals are compared to a target time to obtain a difference therebetween. A rotation speed of the capstan motor is compensated based on the obtained difference to control the rotation speed of the capstan motor.
