  • METHOD OF MANUFACTURING A MAGNETIC HEAD WITH FLUX SHAPING LAYER
    Publication number: 20070103813
    Abstract: A method for fabricating a magnetic head includes forming a first pole and a flux shaping layer in spaced relation to the first pole. A nonmagnetic layer is formed adjacent the flux shaping layer and positioned on an air bearing surface (ABS) side of the flux shaping layer. A tapered recess is created in the nonmagnetic layer, the taper of the recess increasing (i.e., becoming deeper) towards the flux forming layer. The recess is filled with a magnetic material. A probe layer is formed such that it is in electrical communication with the magnetic material filling the recess.
    Type: Application
