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.
