Patent ID: 8432642

Claim:
A magnetic head suspension comprising a load bending part that generates a load for pressing a magnetic head slider toward a disk surface, a load beam part that transmits the load to the magnetic head slider, a supporting part that supports the load beam part via the load bending part and is swung about a swing center directly or indirectly by a main actuator, a flexure part that is supported by the load beam part and the supporting part while supporting the magnetic head slider, and paired right and left piezoelectric elements that are attached to the supporting part so as to be symmetrical with each other with respect to a suspension longitudinal center line and have expansion and contraction directions different from each other, in order to enable micro motion of the magnetic head slider in a seek direction, wherein the supporting part includes a proximal end section that is directly or indirectly connected to the main actuator, a distal end section to which the load bending part is connected, an open section that is positioned between the proximal end section and the distal end section in a suspension longitudinal direction, and paired right and left connecting beams that are positioned on both sides of the open section in a suspension width direction and connect the proximal end section and the distal end section, wherein each of the paired piezoelectric elements has proximal and distal ends that are connected to the proximal end section and the distal end section, respectively, while being at least partially overlapped with the open section in a plan view as viewed along a direction perpendicular to the disk surface, and wherein a suspension width central portion of a proximal edge of the distal end section is formed into a concave shape in a plan view so as to be located on the most distal side in the suspension longitudinal direction at its center that is crossed with the suspension longitudinal center line as well as to be brought closer to the proximal side in the suspension longitudinal direction as extending outward in both sides in the suspension width direction from the center.
