Magnetic head with magneto-resistance effect element disposed on opposite side of magnetic core pair from recording coil |
摘要 |
A magnetic head has a recording magnetic yoke on the side of an air bearing surface of which a recording magnetic gap film is interposed and a reproducing magnetic yoke on the side of an air bearing surface of which a reproducing magnetic gap film is interposed. The magnetic yoke can serve concurrently for recording/reproducing. A recording coil supplying a recording magnetic flux to a recording medium through a recording magnetic yoke is disposed along one main surface of a magnetic yoke. An MR element in which a signal magnetic flux is led from a recording medium through a reproducing magnetic yoke is disposed along the other main surface on opposite side from a recording coil of a magnetic yoke. Or, at least on extension of a film plane of a magnetic gap film, a ferromagnetic layer is disposed so as for a film plane to exist in almost perpendicular direction relative to the film plane. According to such a head structure, reproducing sensitivity decrease of the reproducing MR head due to noise or occurrence of recording fringe can be suppressed.
