1. A method for fabricating a magnetic transducer comprising the steps of:

  • providing a substrate having a release layer formed on a surface thereof, said substrate and release layer defining a pit having sidewalls;

    forming a vertical wall of a nonmagnetic material in said pit with its ends supported by the sidewalls of the pit;

    forming first and second pole pieces of a magnetic material, said pole pieces each having a pole tip disposed in the pit in opposing relationship to each other separated by said vertical wall disposed therebetween defining a magnetic gap;

    magnetically coupling the pole pieces; and

    separating the substrate from the magnetic transducer formed thereon by removing the release layer.
