Laminate and wear-resistant thin-film magnetic head assembly formed thereon.

摘要

A wear-resistant thin-film magnetic head assembly (50) and method of making same. The head assembly includes a wear-resistant layer (56) of diamond-like carbon and a substrate (52) 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 (54) on the substrate. A second adhesion promoting layer (58) can be deposited onto the diamond-like carbon layer to facilitate the deposition of electromagnetic circuitry (62) 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.
