Magnetic disk apparatus
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.
