Abstract

PURPOSE:To stably and accurately scan a rotary magnetic head on a recording track, by driving a tracking actuator by a tracking error signal in a period to reproduce a signal, and varying the length of a magnetic tape from a capstan to a rotary drum. CONSTITUTION:In reproduction, a post actuator 6b is driven according to the tracking error signal detected by a tracking error signal detecting means 13, and the position of a tracking guide post P7 is controlled, then, the position in the longitudinal direction of the magnetic tape 3 at a rotary drum part 5 can be varied. For such variation, a tension control means P2 operates so as to keep the tension of the magnetic tape 3 constant. Thereby, it is possible to keep the satisfactory contact of the rotary magnetic heads 5a and 5b with the magnetic tape 3, and to reproduce the signal stably.
