Abstract
A process of forming a microactuator for positioning a transducing head over a selected radial track of a rotatable disc in a disc drive system is disclosed. A tub is etched in a substrate, and a bottom coil layer is plated at least partially in the tub. A first insulating layer is deposited on the bottom coil layer. A ferromagnetic core layer is formed on the first insulating layer. A second insulating layer is deposited on and around the ferromagnetic core layer. A top coil layer is plated on the second insulating layer, and contacts the bottom coil layer at a point spaced from the ferromagnetic core. A rotor is formed on a rotor substrate to confront the ferromagnetic core, is operatively attached to the slider and is movable with respect to the ferromagnetic core.
