  • Patent number: 8446697
    Abstract: In a magnetic head suspension according to the present invention, each of paired right and left connecting beams that are positioned on both sides of an open section, with which paired piezoelectric elements are at least partially overlapped in a plan view, in a suspension width direction and connect a proximal end section that is directly or indirectly connected to a main actuator and a distal end section to which the load bending part is connected includes proximal-side and distal-side beams. The distal-side beam is inclined with respect to the proximal-side beam in a plan view such that a connection point between the proximal-side and distal-side beams is located closer to a suspension longitudinal center line relative to a virtual line connecting the proximal end of the proximal-side beam and the distal end of the distal-side beam.

    Abstract: In a magnetic head suspension, a piezoelectric element is disposed within a supporting part's open section so that at least a part of its distal-side end surface faces a distal-side wall surface of the supporting part's distal end section forming a distal-side gap between the distal-side end surface and the distal-side wall surface and at least a part of its proximal-side end surface faces a proximal-side wall surface of the supporting part's proximal end section forming a proximal-side gap between the proximal-side end surface and the proximal-side wall surface in a state where the piezoelectric element's upper and lower electrode layers do not face the supporting part and any rigid members that are fixed to the supporting part. The piezoelectric element is fixed to the supporting part by a distal-side insulative adhesive agent and a proximal-side insulative adhesive agent.
