Abstract

Apparatus and method for simultaneously adjusting the gram load and radius geometry height of a head suspension by scanning a spring region of the head suspension with a laser beam. The incremental height difference between left and right legs of a spring region of the suspension may also be concurrently corrected. Apparatus and method for measuring the radius geometry height are provided by two or more non-contacting optical probes. A nitrogen atmosphere may be maintained in the region scanned.
