In a rotary magnetic head device for recording, the rotary head cylinder is configured to trace a control signal track of the magnetic tape so that the phase is shifted by a predetermined angle with respect to the rotational direction with respect to each video head during recording. A rotating magnetic head device comprising: a control head attached to the lower rotating cylinder. (2) The rotary magnetic head device according to claim 1, wherein the control head is installed at a position to scan a control track located below a video signal track for one field being recorded and reproduced. . (3) The rotating magnetic head device according to claim 1, wherein the control head is provided at a lower end of the magnetic tape running path of the lower rotating cylinder.
