Abstract:
An inverted hybrid type thin film magnetic head comprises:a substrate having a surface in which a recessed portion is formed; an inductive recording element formed to be opposed to said surface of the substrate in which said recessed portion is formed; and a magnetoresistive reading element formed on a side of said inductive recording element which is opposite to said substrate; wherein said inductive recording element includes: a first magnetic film formed on said recessed portion of the substrate and having a pole portion which is formed on the substrate and extends from the recessed portion up to an air bearing surface; a thin film coil formed within said recessed portion and having a plurality of conductive turns; a coil supporting and isolating insulating film formed within said recessed portion such that said conductive turns of the thin film coil are supported and isolated by said coil supporting and isolating insulating film; a gap film made of a non-magnetic material formed at least on said pole portion of the first magnetic film; a second magnetic film formed on said gap film and having a pole portion which is opposed to said pole portion of the first magnetic film via said gap film and a portion which is magnetically coupled with said first magnetic film at position remote from said pole portion; and two conductors each having one ends connected to respective ends of said thin film coil; said magnetoresistive reading element includes: a first shield gap film formed on said second magnetic film; a magnetoresistive film formed on said first shield gap film such that a side edge of the magnetoresistive film is exposed on said air bearing surface; a second shield gap film formed on the magnetoresistive film and first shield gap film; and a third magnetic film formed on said second shield gap film and having a portion which is opposed to said magnetoresistive film via said second shield gap film; and at least two bonding pads formed on a side wall of said substrate on a side from which a bearing air flow exits, one of said bonding pads being connected to one of said two conductors which is connected to one end of the thin film coil and being provided above the thin film coil such that a center of the relevant bonding pad situates within a pattern of the thin film coil.
