Abstract:
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.
