  • Manufacturing method of a side core type magnetic head slider
    Patent number: 6553648
    Abstract: A method of manufacturing magnetic head slider including a ferrite core having read/write gap and a housing formed on non-magnetic material having a rail on a surface opposite to a magnetic recording medium. The ferrite core and the housing are bonded to each other. A core bond bar constituted by a continuation at least two cores and a stick-shaped for the housing are bonded to each other ten fine machined. After the fine machining, the bar is cut into individual magnetic head sliders.

  • Hybrid type magnetic head slider having a thin film coil
    Patent number: 6008967
    Abstract: A magnetic head slider including two housing portions made of non-magnetic material, each portion having a rail on a surface thereof to face a magnetic recording medium and generate a floating force. One of the housing portions houses a core part, and the other housing portion houses a coil part. A magnetic core is disposed in the housing, i.e., A gap of the core part for reading/writing is positioned nearly flush with an upper surface of each rail.
