Abstract
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:
