摘要： A magnetic disk apparatus of the present invention is equipped with a microactuator for micro motion using piezoelectric elements in addition to a coarse adjustment actuator such as a voice coil motor or the like, eliminates parts that slide between the microactuator and surrounding members, and alleviates stress on the piezoelectric elements even if an impact is given to the magnetic disk apparatus. Thus, a first actuator fixing portion on a carriage side and a second actuator fixing portion on a magnetic head side of a microactuator mounting portion are coupled with a plurality of flexible coupling portions and coupling portions are placed outside the microactuator in substantially symmetric with respect to a centerline in a longitudinal direction of a suspension.

摘要： By increasing the gain of a controller for coarse motion CFBV within a frequency band in which the gain of a sensitivity function SP=1/(1+PP·CFBP) of fine motion actuator DP and controller for fine motion CFBP exceeds 0 dB, the gain of a sensitivity function SV=1/(1+PP·CFBV) of coarse motion actuator PV and coarse motion controller CFBV is decreased. Through this, in a two-stage actuator control system, a disk apparatus can be provided in which a sensitivity function SPES=1/(1+PP·CFBP)·1/(1+PP·CFBV) indicative of a disturbance compressive ratio in a signal path ranging from disturbance components to a head position error signal is rendered to be 0 dB or less at all frequencies concerned.
