Abstract:
A method and system for providing a magnetic transducer for recording to media is described. The method and system include providing a first pole, a main pole, an auxiliary pole, and at least one coil. The main pole has a first media-facing surface including a recessed portion and a write portion. The auxiliary pole is magnetically coupled with the main pole and has a second media-facing surface. The second media-facing surface includes a first portion and a second portion. The first portion is in proximity to the write portion of the first media-facing surface of the main pole. The second portion is in proximity to and recessed from the recessed portion of the first media-facing surface of the main pole. The coil(s) are for energizing the main pole.
