  • Wear resistant magnetic write head
    Patent number: 6373656
    Abstract: A head design that reduces wear at the leading and trailing edges where the tape contacts the head while minimizing any adverse effects on the performance of the head. In one embodiment of the invention, a localized layer of wear resistant material is formed on the leading edge where the tape contacts the head before passing over the head recording surface. In a second embodiment, the leading edge is formed as wear resistant material embedded in the head structure adjacent to the recording surface. And, in a third embodiment, the leading edge is formed as a wear resistant material strip affixed to the side of the head structure. For each embodiment, the wear resistant material may also be applied in the manner described to the trailing edge where the tape may also contact the head after passing over the recording surface.
    Type: Grant
