Title: Thin-film magnetic head provided with smear-preventing layer

Abstract: A magnetic head including an MR head and a write head exposed to a medium-sliding surface. The MR head includes a magnetoresistive element and slides over a magnetic recording medium to read information magnetically recorded in the magnetic recording medium. The MR head further includes a shield layer and a shield core layer which includes a shield section and a core section. 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 farther than at least the core section. The write head includes a gap layer and a thin-film coil section deposited in that order on the shield core layer, and a magnetic core layer deposited over the gap layer and the thin-film coil section so as to be insulated from the thin-film coil section.
