    摘要： A method for manufacturing a magnetic write head having a stepped trailing shield. The stepped trailing shield is formed by forming a non-magnetic bump over a write pole prior to electroplating a wrap-around magnetic shield. The method allows the location of the front edge of the bump relative to the back edge of the wrap-around shield to be monitored by measuring the electrical resistance of an electrical lapping guide formed concurrently with these features. This concurrent formation of a lapping guide can be used to define the relative location of other features as well, such as the location of a back edge of a wrap-around shield relative to a flare point of a write pole.

    摘要： The present invention discloses a method for the production of sub-micron structures on magnetic materials using electron beam lithography. A subtractive process is disclosed wherein a portion of a magnetic material layer is removed from the substrate using conventional lithography, and the remaining portion of the magnetic material layer is patterned by e-beam lithography. A additive process is also disclosed wherein a thin magnetic seed layer is deposited on the substrate, a portion of which is removed by conventional lithography and replaced with a non-magnetic conducting layer. The remaining portion of magnetic seed layer is patterned by e-beam lithography and the final magnetic structure produced by electroplating.
