ABSTRACT:
Reproducing apparatus for magnetic tape in which the forward and rewind torques motors are series-interconnected to moderate their torques and limit the tape tension during play mode only, thereby eliminating the large heat-generating resistors required when the torque motors are parallel-connected by the conventional arrangement. Relatively small variable resistor means is provided in the power supply to the series-interconnected torque motors, enabling adjustment of tape tension in the play mode. In the specific embodiment illustrated, the variable resistor means comprises two individual resistors. Switch means selectively connects one or both resistors into the torque motor power supply circuit to keep tape tension within a predetermined range during play mode for different size tape reels.
