ABSTRACT:
A method for adjusting the load of a head suspension for supporting a read/write head over a disk in a magnetic disk drive. The suspension includes a load beam having a rigid region and proximal and distal ends, with a base on the proximal end and a flexure on the distal end. A spring region is located between the base and rigid region of the load beam. The spring region includes a pair of arms which extend between the base and rigid region to form a cutout, and a plurality of load adjustment frets which extend across the cutout between the base and rigid region. One or more of the frets can be severed by a laser beam to lower the gram load of the suspension. The gram load of the suspension can be increased by shrinking the frets through exposure to the laser beam. Gram load adjustments can be made with the suspensions in a disk stack assembly by directing the laser beam to the frets through an optical fiber.
