摘要： PURPOSE:To eliminate the need of a tension sensing mechanism on a take-up side by controlling a take-up reel motor so that the reference value and the measured value of the variation of the rotating speed of the take-up reel in a specified time may be made equal. CONSTITUTION:The tension sensing mechanism 18 is provided only on the side where a magnetic tape 1 is taken up in a reverse direction, for example, in tape traveling. When the tape 1 is taken up in a forward direction, the necessary take-up torque of the reel motor 17 on the take-up side is obtained based on a tape supply quantity to the reel 14 on the take-up side in the specified time which is calculated from a tape traveling speed and the radium of the reel 14 at that time and it is taken as the reference value. Meanwhile, based on the variation of the rotating speed of the take-up reel motor 17 in the specified time and the radium of the reel 14 at that time, the take-up torque(measured value) of the reel motor on the take-up side at that time is obtained. Then, the reel motor 17 is controlled so that the reference value and the measured value of the take-up torque of the reel motor 17 may be made equal. Thus, a tape traveling path is simplified.

摘要： PURPOSE:To suppress the damage of a tape to a minimum by switching a generating torque control circuit so as to keep the revolution speed of a take-up side reel motor constant when no regenerative control signal exists. CONSTITUTION:A control(CTL) signal regenerated with a CTL head 2 at the time of feeding the tape at high speed, after being amplified by an amplifier 3, is supplied to a velocity control means 4, and a velocity control signal is formed, and inputted to a reel motor driving circuit 34(35) via a low-pass filter (LPF) 7, and the generating torque of a reel motor 30(31) is controlled, and tape feed speed is controlled. Meanwhile, the CTL signal is supplied to a CTL signal detecting means 5, and the cycle of a regenerative CTL signal is detected, and the generative CTL signal exceeding a prescribed cycle is judged as a signal nonrecording part. When the tape arrives at the signal nonrecording part, the reel motor 30(31) is controlled so as to be rotated at constant revolu tion speed. In such a manner, it is possible to suppress the damage of the tape received at the time of feeding the tape at high speed to a minimum.
