Stepped disc drive voice coil actuator acceleration for reducing resonance of head level micro-actuators

摘要

A disc drive having a voice coil actuator with an attached suspension and head, the head including a micro-actuator. The micro-actuator having at least one natural frequency and at least one natural frequency time period. The voice coil actuator is adapted to attenuate a resonance of the micro-actuator at the at least one natural frequency using a stepped acceleration.
