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, at least one coil and at least one auxiliary pole. The main pole is for providing a magnetic field for recording to the media. The coil(s) are for energizing the main pole. The auxiliary pole is magnetically coupled with the main pole. The shield(s) are for magnetically isolating a portion of the magnetic transducer. At least one of the first pole, the auxiliary pole, and the at least one shield includes a composite magnetic material including a plurality of ferromagnetic grains in an insulating matrix.
