Patent ID: 7242547

Claim:
A magnetic head device having a plurality of recording head elements scanned to a magnetic recording medium, the recording head elements sequentially laminated on a base through insulating layers and the laminated recording head elements disposed to be deviated in a direction perpendicular to a laminating direction of the recording head elements so that when the recording head elements are scanned to the magnetic recording medium, the plurality of the recording head elements form a plurality of recording tracks aligned in a direction perpendicular to the scanning direction of the head, wherein the plurality of recording head elements are formed so that the size in a track width direction of a first magnetic core layer positioned at a preceding side in the scanning direction of the head of a pair of magnetic core layers opposed via a magnetic gap becomes smaller than the size in a track width direction of a second magnetic core layer positioned at an opposite side to the first magnetic core layer in a medium opposed surface opposed to the magnetic recording medium and the ends of the first magnetic core layers of adjacent recording head elements are superposed by a predetermined width as seen from the laminating direction.
