ABSTRACT:
A method and apparatus for imparting a predetermined tension to a tape transported at a predetermined velocity from one to the other of reels mounted on a pair of reel spindles at least one of which is rotated by a motor to have a rotational torque imparted thereto. A signal is provided which has a frequency proportional to the number of revolutions of the reel spindle; an impulse is produced which has a frequency corresponding to the frequency of said signal; a reference voltage is integrated for a time corresponding to the period of said impulse; the peak value of a signal resulting from said integration is sample-held in accordance with said impulse; and a signal resulting from said sample-holding is applied to the motor, thereby imparting a predetermined tension to the tape.
