ABSTRACT:
The present invention is a magnetic disk drive head suspension of the type having a load beam and a flexure, including an alignment measurement pattern on either the load beam or the flexure. The flexure is mounted to a distal end of the load beam, and the alignment measurement pattern is used to evaluate and quantify the position of the flexure relative to the load beam. The alignment measurement pattern includes a plurality of openings adjacent a tooling reference hole that are sized and positioned to expose the outer perimeter of a corresponding tooling reference hole. In this manner, the alignment measurement pattern provides an accurate assessment of the alignment between the load beam and the flexure by indicating the offset of the flexure tooling hole relative to the load beam tooling hole.
