。[Claim for Utility Model Registration] A control voltage is output from a reel motor speed control means for controlling the rotational speed of the reel motor to a take-up reel motor driver, and the take-up reel motor driver drives the take-up reel motor. In the magnetic recording and reproducing apparatus, the magnetic tape is run by the magnetic tape, and the supply reel motor is controlled according to the voltage applied to the supply reel motor driver to apply back tension to the magnetic tape. Tension control means for inverting and outputting a control voltage output by the speed control means and applying it to the supply side reel motor driver, and controlling the back tension applied to the magnetic tape according to the output voltage of the tension control means. A magnetic recording/reproducing device characterized by:
