  • Method for actively controlling the gram load on a disk drive suspension assembly
    Publication number: 20030074783
    Abstract: A method and apparatus for actively controlling the gram load on a disk drive suspension assembly and to a disk drive using the present disk drive suspension assembly. The gram load can be actively changed by changing the applied voltage to one or more multi-layer piezoelectric actuators attached to the head suspension. The active gram control system allows the gram load to be changed on a non-permanent basis and to control the gram load to a much finer scale than can be accomplished using conventional techniques. The disk drive suspension that uses a piezoelectric actuator having two or more layers. Each layer of the multi-layer piezoelectric actuator is poled in such a fashion that when energized, some piezoelectric layers contract while others expand, resulting in a curling motion.
