Abstract: An enchance recording head design provides conduction and mechanical restraint control in order to minimize the pole tip protrusion and the head temperature resulting from the thermal heating of the magnetic recording head during operation. In one embodiment, the recording head includes a hybrid diffuser formed within an insulation layer, at a predetermined distance from the head write section. The hybrid diffuser is comprised of a thermal conduction layer with high thermal conductivity, such as gold or copper, and a mechanical restraint layer having near zero CTE, such as a 60-80% face-centered-cubic NiFe (Invar) material. The hybrid diffuser is recessed from the ABS to prevent the delamination of the hybrid diffuser due to the otherwise displacement incompatibility between the inner insulating layer and the hybrid diffuser at the ABS.

Abstract: A microactuator comprised of a piezoelectric motor mounted on a flexure tongue with offsetting hinges, to perform a fine positioning of the magnetic read/write head. The substantial gain in the frequency response greatly improves the performance and accuracy of the track-follow control for fine positioning. The simplicity of the enhanced microactuator design results in a manufacturing efficiency that enables a high-volume, low-cost production.

Abstract: A microelectromechanical (MEM) actuator incorporates a dual-stator design operated electrostatically in conjunction with a rotor to affect a fine positioning of a thin film magnetic read/write head. The substantial gain in the frequency response bandwidth greatly improves the performance and accuracy of the track-follow control for fine positioning of the thin film read/write head. The stators are comprised of a plurality of electrodes arranged perpendicularly along a plurality of stationary radial spokes, which are interleaving and oppositely disposed to the same plurality of moveable radial spokes formed on the rotor. A track-follow control commands a voltage to be supplied to the rotor and stators, thereby inducing an electrical potential field to generate an electrostatically attractive force for each pair of radial spokes between each of the stator and the rotor.

Abstract: In one aspect, an inductive transducer is disclosed having a leading pole layer and a leading pole tip, with the pole layer being further removed than the pole tip from a media-facing surface. In another aspect, an inductive transducer is disclosed having a magnetic pedestal disposed between a leading pole layer and a leading pole tip, with at least one of the pedestal and pole layer being further removed than the pole tip from a media-facing surface. In another aspect, a leading pole layer or pedestal may have a surface that slopes away from the media-facing surface with increasing distance forward from the leading pole tip.
