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.

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.

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.

A method for producing sliders without alumina overcoat protrusion on the air bearing surface. The method comprises a method for removing alumina protrusion on the air bearing surface of a slider comprising contacting the air bearing surface of the slider with an aqueous base having a pH of about 9 to about 11.
