Patent ID: 8064167

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 through the load bending part, and a flexure part that includes a head-mounting region for supporting the magnetic head slider and that is fixed to the load beam part, wherein the supporting part includes a main body region, and a pair of supporting pieces that extend from both ends of the main body region in a suspension widthwise direction toward a distal end side of the suspension so as to define a concave region between the pair of supporting pieces that is opened toward the distal end side of the suspension, the pair of supporting pieces being symmetrical to each other about a longitudinal center line of the magnetic head suspension, wherein the load bending part includes an elastic plate that is supported at both ends by the pair of supporting pieces, wherein the elastic plate includes first and second supporting-part contacting regions that are brought into contact with and fixed to the pair of supporting pieces, respectively, a load-beam-part contacting region that is fixed to the load beam part within the concave region, and first and second extending regions that connect the load-beam-part contacting region with the first and second supporting-part contacting regions, respectively, the first and second extending regions being elastically twisted around a load bending center line along the suspension widthwise direction so that the elastic plate functions as the load bending part, wherein the load beam part is formed by a load beam base plate, a portion of the load beam base plate that is positioned on a distal end side from the load bending center line including a parallel region that extends substantially in parallel with the load-beam-part contacting region and directly or indirectly fixed thereto, an intermediate region that extends from the parallel region toward a distal end side of the suspension through a proximal-side bending line along the suspension widthwise direction, and a distal region that extends from the intermediate region toward a distal end side of the suspension through a distal-side bending line along the suspension widthwise direction and that includes a dimple with which the head-mounting region is brought into contact, and wherein the distal-side bending line is positioned in the vicinity of an intermediate point between the load bending center line and the dimple in a suspension lengthwise direction.
