  • Patent number: 7114241
    Abstract: A method of manufacturing a magnetic head device includes forming a thin film magnetic head element over a substrate, the thin film magnetic head element including a magnetoresistance (MR) element. The substrate is cut such that the MR element is exposed on a side surface of the substrate. The side surface is then polished. Afterward, a magnetically degenerated layer is removed from the thin film magnetic head element along the side surface. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Publication number: 20030074785
    Abstract: An apparatus and method for manufacturing magnetic head device. In one embodiment, the magnetic head device includes a thin film magnetic head element having a reproduction element part comprised of a magnetoresistance effect element formed by layering on one surface of a slider. The magnetoresistance effect element is exposed on a side to oppose a magnetic recording media. Dry etching is used to remove a degenerated layer produced on the exposed side of the magnetoresistance effect element by polishing the surface of the side opposing the magnetic recording media.
