摘要： A thin film magnetic head includes an insulating layer having a trench which has a track-width region formed with a track width Tw, and an inclined region having inclined surfaces formed to gradually increase the width dimension of the trench from the track-width region to the surface of the insulating layer. An upper core layer is formed on the inclined surfaces to relieve magnetic flux saturation and suppress the occurrence of write fringing. A lower pole layer, a gap layer, and an upper pole layer are previously formed in the trench of the insulating layer, thereby permitting the formation of a resist layer to a uniform thickness. By using the resist layer, inclined surfaces can be formed in a predetermined shape in the insulating layer with high reproducibility. Therefore, the upper core layer formed on the inclined surfaces can be appropriately separated from the lower pole layer, thereby suppressing the occurrence of write fringing.

摘要： The lower core layer 7 is formed in approximately constant thickness at the portion confronting the upper core layer so that its thickness gradually reduces toward its side edge. Therefore, the thickness of the layer of the non-magnetic material 8 formed on the lower core layer 7 becomes uniform, stabilizing the coil layer formed thereon. An excellent material of soft magnetic materials can be used since the lower core layer 7 is formed by sputtering, enabling to record at a high frequency.

摘要： A longitudinal bias layer and an electrode layer are formed on a non-magnetic material layer. The longitudinal bias layer and the electrode layer are partially removed by an etching technique so that a narrow gap defining the track width Tw is formed in the longitudinal bias layer and the electrode layer. Furthermore, a three-layer film consisting of, from bottom to top, a magnetoresistance effect layer, a non-magnetic layer, and a transverse bias layer, or otherwise a spin valve film consisting of a free magnetic layer, a non-magnetic layer, a fixed magnetic layer and a bias layer is formed on the above structure. The three-layer film or the spin valve film is then partially removed by an etching technique so that the three-layer film or the spin valve film remains only in the above-described narrow gap formed in the longitudinal bias layer and the electrode layer. The shape of the side walls of the three-layer film or the spin valve film is precisely determined by the side walls of the longitudinal bias layer and the electrode layer. The resultant three-layer film or the spin valve film exhibits excellent magnetic detection characteristics. Furthermore, the longitudinal bias layer has good magnetic coupling with the magnetoresistance effect layer.
