。 The control pulses used to control the rotation of the capstan motor for running the tape record on a magnetic tape with polarities alternating between positive and negative. A tape running servo device that runs at a constant speed so as to maintain a phase relationship and is used for normal playback by a rotating magnetic head, which substantially inverts the polarity of the control pulse during reverse playback, and combines the negative polarity control pulse with the servo reference. A tape running servo device having a polarity inversion circuit that performs tape running servo according to the phase relationship of signals.
