ABSTRACT:
A high-speed tape transport system in a magnetic reproducing apparatus. The reproducing apparatus includes a reel for taking up a magnetic tape on which an information signal and a control signal have been recorded. The system comprises a control head for reproducing the control signal from the magnetic tape, a frequency-voltage converter for producing a voltage corresponding to the frequency or period of the control signal thus reproduced. Moreover, the system includes a reel motor for rotating the reel and a circuit for controlling the reel motor's rotational speed in response to the voltage produced by the frequency-voltage converter. Consequently, the rotational speed of the reel motor is controlled so that the magnetic tape is travelled at a constant high speed.
