ABSTRACT:
A rotary magnetic head device comprises a rotary body mounted with rotary magnetic heads which rotate while scanning over a traveling magnetic tape, where the heads scan over tracks formed obliquely with respect to the longitudinal direction of the tape to reproduce recorded signals, a bearing mechanism for bearing the rotary body in a freely rotatable state and so that the rotary body is freely displaceable along an axial direction thereof, and a displacing mechanism for displacing the rotary body along the axial direction thereof so that the heads follow and scan over the tape.
