Adhesive attachment features for bonding piezoelectric motors to a load beam substrate. The attachment features have one or more reliefs under or partially under or adjacent to a piezoelectric transducer to control the flow of adhesive by limiting or influencing adhesive travel or flow and simultaneously preventing excessive adhesive fillet height adjacent the piezoelectric motor while simultaneously providing for improved bond strength between the piezoelectric element and the load beam.

Enhancements for adhesive attachment of piezoelectric motor elements to a disk drive suspension

A computer controlled regram machine for adjusting the loads on head gimbal assemblies to bring the loads within a desired specification window defined by upper and lower window specifications. The regram machine includes a load cell for measuring actual gimbal assembly loads, a mechanical bending mechanism for implementing mechanical adjust procedures to increase and decrease the gimbal assembly loads, and a heat source for implementing light adjust procedures to decrease the gimbal assembly loads. The algorithm executed by the machine includes:
