Abstract

PURPOSE:To enable a relative locus and a head locus to coincide each other on a tape even when the magnetic tape is run at a high speed by changing a phase difference between a head switching signal and a signal showing the rotary phase of a rotary drum according to the rotation number of the rotary drum. CONSTITUTION:A set of head 5 is opposedly provided on the rotary drums 2 and 3, the head switching signal for successively switching a signal reproduced by a set of head 5 based on the signal showing the rotary phase of the drums 2 and 3 is generated and the signal showing the rotary phase of the drums 2 and 3 and the head switching signal are controlled to change their phase difference according to the rotation number of the drums 2 and 3. By changing the phase difference between the head switching signal and the signal showing the rotary phase of the rotary drum in that way, the relative locus and the head locus can be made to coincide each other when the magnetic tape is run at a high speed.
