Abstract:
1. A device for detecting a position of a dimple formed on a load beam of a disk drive suspension, the dimple having substantially a dome shape of a circular-arc rotor such that a top of the dimple is substantially located at a center of the dimple, and the dimple having a concave back surface, the device comprising: a workpiece fixing jig for holding the disk drive suspension to be inspected, wherein the disk drive suspension holdable by the workpiece fixing jig includes the load beam and a flexure which is fixed to the load beam, the flexure comprising a tongue portion which is in contact with the top of the dimple; an illumination device which directs illumination light toward the back surface of the dimple along an axis of the dimple of the disk drive suspension which is holdable by the workpiece fixing jig; an imaging device which acquires an image of light reflected by the back surface of the dimple along the axis of the dimple, the reflected light having a peak which appears in a position corresponding to the top of the dimple; and an image processing section which processes the image acquired by the imaging device; wherein the image processing section includes:
