  • Magnetic head and magnetic disk apparatus
    Patent number: 7142393
    Abstract: An MR head includes a slider, and a film structure part which is located on an air outflow side of the slider and includes an MR element for reproducing. The film structure part has an end surface located on an identical side as a floating surface of the slider. The end surface of the film structure part and the floating surface of the slider form a step-like recess which has a depth making it possible to prevent a fine projection on a magnetic disk from hitting the end surface of the film structure part.
    Type: Grant
    Filed: July 3, 2001
    Date of Patent: November 28, 2006
    Assignee: Fujitsu Limited
    Inventors: Koki Kanda, Minoru Takahashi, Katsumi Kiuchi, Takao Koshikawa, Katsuhide Sone, Muneo Kamiguchi

  • Method of manufacturing a magnetic head
    Patent number: 5634259
    Abstract: A thin-film element is formed at an end of a core slider, at which end air exits, and a protective film is formed on the thin-film element. A step-like recess is formed in the protective film near the thin-film element so as to extend longitudinally toward an end at which air exits.
