  • Method of manufacturing a magnetic head
    Patent number: 8146237
    Abstract: In a magnetic head manufacturing method, a floated surface of each block having plural magnetic head elements formed and arranged on a substrate is ground and lapped in a grinding/lapping step. The grinding/lapping step contains an angle adjusting step for adjusting the angle of the floated surface of the block with reference to a magnetic-head-element formed surface of a substrate and grinding the floated surface concerned, and a finishing lapping step of lapping the floated surface at an angle adjusted in the angle adjusting step.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: April 3, 2012
    Assignee: SAE Magnetics (H.K.) Ltd.
    Inventors: Yoshiaki Ito, Osamu Fukuroi, Hiroyasu Tuchiya, Kenji Kodaka

  • Magnetic head manufacturing method, magnetic head, angle setting device and lapping device
    Publication number: 20060103990
    Abstract: In a magnetic head manufacturing method, a floated surface of each block having plural magnetic head elements formed and arranged on a substrate is ground and lapped in a grinding/lapping step. The grinding/lapping step contains an anglea djusting step for adjusting the angle of the floated surface of the block with reference to a magnetic-head-element formed surface of a substrate and grinding the floated surface concerned, and a finishing lapping step of lapping the floated surface at an angle adjusted in the angle adjusting step.
