Abstract
A rotary head device for a recording and reproducing apparatus includes a rotary drum and a stationary drum. The rotary drum has a guide surface formed of a conical surface coaxial with the axis of rotation of the rotary drum and wound with a magnetic tape. A head unit is mounted on the rotary drum to be rotatable integrally therewith. The head unit includes two head elements facing each other, for scanning the tape wound on the guide surface, while the tape is being interposed between the head elements, as the rotary drum rotates.
