Abstract
A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a write pole and a coil. The write pole has a pole tip and a yoke. The coil energizes the write pole and includes a plurality of turns. A turn of the plurality of turns has a first portion and a second portion. The first portion has a first length in a stripe height direction substantially perpendicular to the ABS. The second portion has a second length in the stripe height direction. The second length is greater than the first length and extends at least to at least one adjacent turn.
