A suspension is provided for improving reliability in reading/writing of data by improving stiffness in a longitudinal direction of a flexure while realizing low pitch/roll stiffness of a tongue part. The suspension includes: a flexure, including two branched outrigger parts extending to the tip side of the flexure, and a tongue part for mounting a magnetic head slider, located between the outrigger parts and linked to the tip sides of the outrigger parts; a trace formed on the flexure; and a fixed part in which at least a part of a bent part formed in the trace is fixed to the tongue part.

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.
