Abstract:
A thin film magnetic head, comprising:a first magnetic layer having a pole portion which is to be opposed to a magnetic record medium;a second magnetic layer having a pole portion which constitutes an air bearing surface together with said pole portion of the first magnetic layer, and being magnetically coupled with said first magnetic layer at a position remote from said air bearing surface;a gap layer made of a non-magnetic material and inserted between said pole portion of the first magnetic layer and said pole portion of the second magnetic layer at least at said air bearing surface;a thin film coil means formed by one or more layer thin film coils and having a portion which is arranged between said first and second magnetic layers by means of an insulating layer;a substrate supporting said first and second magnetic layers, gap layer, insulating layer and thin film coils; andfurther comprising contact pads for inner ends of said first and second thin film coil halves located adjacent to a contact hole such that none of the contact pads is located between another contact pad and the contact hole,wherein at least one layer thin film coil among said one or more layer thin film coils includes first and second thin film coil halves whose coil windings are alternately arranged with interposing an insulating layer therebetween and said first and second thin film coil halves are connected to each other such that an electric current flows therethrough in a same direction.
