ABSTRACT:
A tape traveling apparatus drives differentially a tracking control actuator and a tension control actuator by inputting simultaneously into a tension controller a tracking instruction signal inputted into a tracking controller, and variably adjusts an amplification of the tracking instruction signal inputted into the tension controller according to an output of a tension sensor for detecting a tension variation of a tape, thereby eliminating a differential error between the tracking control actuator and the tension control actuator.
