Abstract
The present invention relates to a method and apparatus for providing improved roll static angle adjustment for head gimbal assemblies (HGA's) used in disc drives. In the method, proximal and distal clamping members are attached to a load beam of the HGA and are separated by a distance of 4-30% of the length of the load beam. One of the distal and proximal clamping members is rotated about a longitudinal axis of the load beam such that the relative angular position of the distal and proximal clamping members reaches an adjust angle. Also disclosed is a rigid beam section of an HGA that includes apertures which are positioned along maximum stress contours where early plastic deformation of the rigid beam section is desired during adjustment of the roll static angle.
