Patent ID: 8174793

Claim:
A thin film magnetic head, comprising: a slider substrate having an air bearing surface (ABS) that configured to provide an appropriate flying height from a recording medium; a magnetic head element formed on a head formation surface that is a side surface relative to the ABS when the ABS is considered as a bottom surface, that is in an approximately rectangular shape that is perpendicular to a track direction; and a plurality of electrode terminals formed on a substantially same surface as the head formation surface on which the magnetic head element is laminated, wherein the plurality of electrode terminals is arranged in an array on a second side of the head formation surface that is opposite a first side on the ABS side from which a functional end of the magnetic head is exposed, the plurality of electrode terminals includes a pad and a protrusion formed along a part of a periphery of the pad, the pad and the protrusion are configured from different materials, and the pad is formed from one of Au, Ag, Cu, Ti and Al, and the protrusion is formed from one of a conductive material and alumina, the conductive material having a lower solder adherence property than the material selected for the pad.
