ABSTRACT:
A head suspension for supporting a head slider over a disk in a dynamic storage device and providing precise movement of the head slider relative to tracks on the disk. The head suspension includes a load beam, a flexure having a slider mounting region, and a dimple interface transmitting a load beam force to the slider mounting region. The head suspension further includes a microactuator mounted to the load beam. Movement of the microactuator is transmitted through the dimple interface by action of frictional forces at the dimple interface so as to cause movement of the slider mounting region transverse to tracks on the disk. A method of precisely moving a head slider supported by a head suspension includes providing and driving a microactuator configured to transmit movement of the microactuator to a slider mounting region through a dimple interface by action of frictional forces at the dimple interface.
