Claims

[Scope of utility model registration request]

(1) a recording or reproducing head, a head stand to which a second recording or reproducing head is fixed, and two sets of electromechanical conversion bimorph elements, the recording or reproducing head traveling in a direction across a recording track; and a head carrier to which the two sets of electromechanical conversion bimorph elements are attached, which are arranged at symmetrical positions with respect to a plane including a direction perpendicular to the recording track plane and are held in a coupled state with the head stand. a long hole provided in the head carrier portion, an axis having approximately the same diameter as the short side of the long hole, which passes through the long hole and is fixed to the head stand, and the head carrier portion a moving mechanism for moving the head across a recording track; and a recording or playback head device.

(2) The recording or reproducing head device according to claim (1), wherein the head stand is fixed to the two sets of electro-mechanical conversion bimorph elements and both are maintained in a coupled state.

(3) The head stand connects the two sets of electrical
The recording or reproducing head device according to claim 1, wherein the recording or reproducing head device is pressed against the mechanical converting bimorph element to maintain the two in a coupled state.
