Abstract:
A disk drive head gimbal assembly includes a laminated flexure with a tongue having an actuated portion that rotates about an axis of rotation by expansion of an adhered piezoelectric element. A non-actuated portion of the tongue adjoins and forms a bridge between two outrigger beams, with a dimple contact location that is in contact with a dimple of the load beam and through which the axis of rotation passes. The piezoelectric element has an anchored end that is adhered to the non-actuated portion of the tongue, and an opposing actuated end adhered to the actuated portion. The actuated portion of the tongue includes first and second head mounting plates that are each adhered to the read head. Each of the head mounting plates is connected to the non-actuated portion of the tongue by an elongated compliant member that is oriented radially with respect to the dimple contact location.
