Abstract
A method and system provide a magnetic recording transducer having air-bearing surface (ABS). The magnetic recording transducer includes a pole, a side shield, a nonmagnetic gap between the side shield and the pole and at least one coil for energizing the pole. The pole has a pole tip proximate to the ABS. The side shield includes at least one nonconformal portion that extends from a throat height in a stripe height direction perpendicular to the ABS and is nonconformal with the pole. The spacing between the nonconformal portion(s) of the side shield and the pole varies based on a distance from the ABS.
