ABSTRACT The present invention is concerned with a helical scan type rotary magnetic head device employed for example in a video tape recorder in which the magnetic tape is caused to run obliquely while it contacts the head and in which recording tracks are formed on the magnetic tape at a predetermined angle of inclination relative to the tape. According to the present invention, the tape guide drum along the side of which the magnetic tape is caused to run while contacting with it has a cut-out at its portion free of contact with the magnetic tape, while a rotary transformer adapted for receiving and transmitting recording and/or reproducing signals at or from a rotary magnetic head is mounted so as to be enclosed within the interior of the tape guide drum to reduce the size and thickness of the rotary magnetic head device.
