Abstract:
A microactuator includes: a base to be joined to a flexure; a pair of arms joined to the base; and PZT devices, mounted on the arms, to be deformed in an expanding or contracting manner based on driving signals applied, and the microactuator holds the side faces of the magnetic head slider between the arms. The length of each arm is set to a length same as or shorter than that of the magnetic head slider in a longitudinal direction.
