    摘要: A magnetic transducer having an air-bearing surface is described. The magnetic transducer includes a nonmagnetic layer on an underlayer, a pole having a plurality of sidewalls, a gap layer on the sidewalls, a seed layer and at least one side shield. The nonmagnetic layer has an aperture therein. The aperture is free of magnetic inclusions at the ABS. The pole is on the underlayer and within the aperture. The seed layer is for the side shield(s) and resides on the gap layer, a portion of the underlayer and a portion of the nonmagnetic layer. The side shield(s) residing on the seed layer and in the aperture. The side shield(s) are free of undercuts at the ABS.

    摘要: A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a main pole and at least one coil for energizing the main pole. The coil(s) have a number of turns. The magnetic transducer also includes at least one shunt coupled to at least one of the number of turns. At least one remaining turn of the number of turns carries a current. The shunt(s) carry a portion of the current from the shunted turn of the number of turns. Thus, the coil(s) have an effective number of turns is less than the number of turns.
