Abstract

The dual-stage disk actuator discussed here uses a voice coil motor (VCM) as a coarse actuator and a piezoelectric actuator (PZT) mounted on VCM as a fine actuator. The mechanism and the control system of the dual-stage actuator was analyzed in this paper and the criterion ofjudging the quality of the dual-stage actuator was received. The behaviors associated VCM with PZT in the process of seeking settling and following are described here also.
