ABSTRACT:
A magnetic head device scanned to a magnetic recoding medium has a plurality of recording head elements laminated on a base via insulating layers, the plurality of recording head elements are formed such that the size in a track width direction of a first magnetic core layer, of a pair of magnetic core layers opposed via a magnetic gap, positioned at a preceding side in a scanning direction of the head becomes smaller than the size in a track width direction of a second magnetic core layer positioned at its opposite side, and the ends of the adjacent first magnetic core layers are disposed to be deviated in a direction perpendicular to the laminating direction to be superposed in a predetermined width as seen from a laminating direction.
