ABSTRACT:
A reel servo device for a video cassette recorder with a direct drive reel system, which carries out smoothly fast forward and fast rewind operations by distributing properly the load carried to the supply reel motor and the take-up reel motor. The current through the driving reel motor, is detected and supplied as a driving current of a magnitude proportional to the detected voltage to the other reel motor so as to rotate it in the direction of the tape movement.
