Patent ID: 8189299

Claim:
A magnetic head suspension comprising: a flexure part including a magnetic head mounting region for supporting a magnetic head slider, a load bending part for generating a load to press the magnetic head slider towards a recording medium, a load beam part for transmitting the load generated by the load bending part to the magnetic head mounting region, and a base part connected to a proximal end side of the load bending part, wherein a region of the base part which extends from a distal end of the base part towards a proximal end side by a predetermined distance and to which the proximal end side of the load bending part is connected is made to be a thin thickness region having a thin thickness compared to an other region, wherein a boundary line between the thin thickness region and the other region is a horseshoe shape in plan view so that its center in the width direction is positioned closer to a proximal end side of the base part, wherein the load bending part includes first and second fixing region portions that are fixed to the base part and a load generating region that is positioned between the first and second fixing region portions and the load beam part, and wherein the first and second fixing region portions are fixed to the base part within a concave part that is formed by the thin thickness region and the other region so as to be opened to a distal end side of the base part.
