ABSTRACT:
A wear-resistant thin-film magnetic head assembly and method of making same. The head assembly includes a wear-resistant layer of diamond-like carbon and a substrate of titanium carbide particles dispersed in an alumina matrix. Adhesion of the diamond-like carbon to the substrate is improved by depositing an adhesion promoting layer on the substrate. A second adhesion promoting layer can be deposited onto the diamond-like carbon layer to facilitate the deposition of electromagnetic circuitry on the diamond-like carbon layer. Diamond-like carbon can be used as an insulator anywhere inside the head assembly. The present invention simplifies the construction of a head assembly and increases its resistance to wear by moving magnetic media.
