Abstract:
A magnetic head comprising an MR head and a write head which are exposed to a medium-sliding surface,the MR head comprising a magnetoresistive element and sliding over a magnetic recording medium to read information magnetically recorded in the magnetic recording medium, the MR head further comprising: a shield layer provided on one side in the thickness direction of the magnetoresistive element; and a shield core layer comprising a shield section and a core section provided on the other side in the thickness direction of the magnetoresistive element, the magnetoresistive element, the shield layer, and the shield section being exposed to the medium-sliding surface, wherein a smear-preventing layer is provided between the shield section and the core section in the shield core layer, the smear-preventing layer protruding from the medium-sliding surface further than at least the core section, the write head comprising: a gap layer and a thin-film coil section deposited in that order on the shield core layer; and a magnetic core layer, which is magnetically coupled to the core section, deposited over the gap layer and the thin-film coil section so as to be insulated from the thin-film coil section, the core section, the gap layer, and the magnetic core layer being exposed to the medium-sliding surface to form a magnetic gap.
