Abstract:
A thin film magnetic head comprising:a first magnetic core layer and a second magnetic core layer, said second magnetic core layer having a tip region including a surface facing a recording medium and another region other than the tip region, said second magnetic core layer being disposed at a trailing side of said magnetic head as compared to said first magnetic core layer; anda coil layer provided between said first and second magnetic core layers for inducing a recording magnetic field to said first and second magnetic core layers;a gap layer disposed on a surface, at the second magnetic layer side, of said first magnetic core layer, the end face of said gap layer being exposed at the surface facing the recording medium; anda nonmagnetic material layer disposed on a surface, at the first magnetic core layer side, of said second magnetic core layer toward the surface facing the recording medium, said nonmagnetic material layer being in contact with said gap layer at the tip region,wherein said gap layer and said nonmagnetic material layer define a magnetic gap at the surface facing the recording medium, andon said nonmagnetic material layer, a magnetic material layer is disposed on a face, at the first magnetic core layer side, of said nonmagnetic material layer, in the region other than the tip region.
