Abstract: A heat extractor to transfer heat generated by the coil of a magnetic read head to a substrate, when there is at least one thermally insulating layer between the coil and the substrate, is disclosed, together with a method for its manufacture.

Abstract: Concerns about inadequate electromigration robustness in CCP CPP GMR devices have been overcome by adding magnesium to the current confining structures that are presently in use. In one embodiment the alumina layer, in which the current carrying copper regions are embedded, is fully replaced by a magnesia layer. In other embodiments, alumina is still used but a layer of magnesium is included within the structure before it is subjected to ion assisted oxidation.

Abstract: The problem of increasing the output signal from a CCP-CPP GMR device without having it overheat has been overcome by placing materials that have different thermoelectric potentials on opposing sides of the spacer layer. Heat from the hot junction is removed at the substrate, which acts as a heat sink, resulting in a net local cooling of the confined current spacer layer, enabling it to operate at both higher input voltage increased reliability.

Abstract: The hydraulic mount assembly is disclosed having a partition forming two hydraulic chambers. A primary chamber is formed by an elastomeric member and a second chamber by a resilient diaphragm. The partition is formed by a pair of plates that define an intermediate cell between the chambers. The partition plates are both formed of conductive material and are connected by a conductor to ground potential. An intermediate plate of conducting material is mounted between the plates within the cell on spaced insulating pads. Preferably, the intermediate plate includes a peripheral skirt extending toward a cooperating continuous channel formed in one of the partition plates so as to form a dome with increased surface area and a tortuous pathway for the flow of fluid through the cell between the primary and secondary chambers. The plates are connected to a control circuit including a system controller with transducers that sense the operating conditions of the vehicle.
