Claims

[Claims for Utility Model Registration] 1. In a rotating head device that records information signals by forming an inclined track on a magnetic tape using a magnetic head attached to a rotating drum, each free end of a pair of electromechanical transducers is provided with a magnetic head. Each head is attached, supported by a support so that the respective free ends are closely opposed to each other, and arranged at a predetermined position on the rotating drum, and a voltage is applied to each of the pair of electromechanical transducers. A rotary head device characterized in that the magnetic head is displaced in a direction perpendicular to the surface of the magnetic tape, and the amount of protrusion of each magnetic head can be controlled respectively. 2. In a rotating head device that forms an inclined track on a magnetic tape by a magnetic head attached to a rotating drum and records information signals, a magnetic head is attached to each free end of a pair of electromechanical transducers, and each of the above-mentioned free fixed to a predetermined position of the rotating drum with an adhesive so that the ends thereof are close to each other and facing each other; applying a voltage to each of the pair of electromechanical transducers to displace them in a direction perpendicular to the surface of the magnetic tape; A rotary head device characterized in that it is configured to be able to control the amount of protrusion of each magnetic head. 3. In a rotating head device that records information signals by forming inclined tracks on a magnetic tape using a magnetic head attached to a rotating drum, a single piezoelectric element plate is divided by notched grooves, and two sections are placed facing each other in the longitudinal center. A relatively movable unit comprising a pair of electromechanical transducers having a pair of free ends and a magnetic head attached to each free end of the pair of electromechanical transducers is arranged at a predetermined position on the rotating drum. The rotation device is configured such that a voltage is applied to each of the pair of electromechanical transducers to displace them in a direction perpendicular to the surface of the magnetic tape, thereby controlling the amount of protrusion of each magnetic head. Head device.
