摘要： A thin-film magnetic head includes a lower magnetic shield layer, an MR multi-layered structure formed on the lower magnetic shield layer so that current flows in a direction perpendicular to surfaces of laminated layers, an upper magnetic shield layer formed on the MR multi-layered structure, and an additional lower magnetic shield layer directly laminated on the lower magnetic shield layer outside both side ends in a track-width direction of the MR multi-layered structure. The additional lower magnetic shield layer is directly contacted with both side surfaces in a track-width direction of the MR multi-layered structure. A top surface of the additional lower magnetic shield layer is positioned higher in height than a top surface of the lower magnetic shield layer in a region where the MR multi-layered structure is formed.
