ABSTRACT:
A recording element is provided for use in a high density thin film recording head. The recording element includes a substrate, a thermally conductive material in contact with the substrate, and an insulative layer in contact with the thermally conductive material. The recording element further includes a magneto-resistive element in contact with the insulative layer such that the magneto-resistive element fails to overlay the thermally conductive material. The thermally conductive material and the insulative layer have thermal conductivities sufficient to dissipate heat from the magneto-resistive element so that heat induced malfunctions of the recording element are minimized. The method for manufacturing the recording element is also provided. The method includes depositing a thermally conductive material in contact with a substrate, depositing an insulative layer in contact with the thermally conductive material, and depositing a magneto-resistive element in contact with the insulative layer such that the magneto-resistive element fails to overlay the thermally conductive material.
