Abstract:
1. A thin-film magnetic head comprising: an insulation gap; first and second yoke layers with first and second ends, respectively, said first ends constituting magnetic poles separated from each other by said insulation gap, said second ends being magnetically coupled with each other; and a coil conductor constituted by a plurality of individual turns, generating a magnetic field and applying the generated magnetic field into said first and second yoke layers, each turn of said coil conductor comprising a first section, a second section with one end coupled with one end of said first section, and a third section with one end coupled with the other end of said second section, said first section passing between said first and second yoke layers in parallel with surfaces of said first and second yoke layers, and extending over said first and second yoke layers, said second section traveling in a direction perpendicular to the surfaces of said first and second yoke layers at a position outside of said first and second yoke layers, and said third section passing outside of said first yoke layer in parallel with the surface of the first yoke layer, and extending over the first yoke layer, wherein said first section and said third section of each turn of the coil conductor include a part traveling in a direction parallel to an air bearing surface of the thin-film magnetic head, and a second part traveling in a direction perpendicular to the air bearing surface, respectively.
