ABSTRACT:
A tape driving apparatus includes circuits for driving a supply reel and a take-up reel, circuits for detecting tape radii on the reels, a circuit for producing take-up side torque information and controlling the take-up reel, a circuit for setting a determining a coefficient of feed torque for the supply reel in accordance with the tape radius information of the supply or take-up reel, a circuit for determining feed torque information of the supply reel from the take-up side torque information, the tape radius information of the supply and take-up reel and the determining coefficient of the feed torque, a circuit for determining back torque information proportional to the tape radius information of the supply reel, a circuit for outputting a torque information change-over signal on the basis of a mode change-over command, the feed torque information and the back torque information, and a circuit for sending either one of the feed torque information and the back torque information to the supply reel driving circuit on the basis of the torque information changeover signal. The roles of the take-up and supply reels can be reversed as needed.
