Abstract
A head actuator for a disk drive is provided with a structural body integrally formed by a housing portion for rotatably supporting a moving part formed by a head for writing/reading data in/from a disk and a coil fixed therewith and a yoke portion for interlinking magnetic flux with the coil, which structural body is fixed to a base portion. By virtue of such structure, the resonance point of a vibration system of the head actuator can be increased in frequency thereby to stably and correctly locate the head on the disk. The structural body and base portion mount to each other on the surfaces which are substantially coplanar with the center of gravity and head arm direction of movement.
