System for providing a transducer having a split main pole

摘要

A method and system for providing a magnetic recording head is described. The magnetic recording head has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The magnetic recording head includes a main pole, at least one auxiliary pole, a nonmagnetic spacer, and at least one coil. The main pole includes a first main pole piece and a second main pole piece. The first main pole piece includes a pole tip occupying a portion of the ABS and a back edge distal from the ABS. The second main pole piece has a front surface. The auxiliary pole(s) have a front recessed from the ABS and are magnetically coupled with the main pole. The nonmagnetic spacer is between the back edge of the first main pole piece and the front surface of the second main pole piece. The coil(s) are for energizing the main pole.

1. A magnetic recording head having an air-bearing surface (ABS) configured to reside in proximity to a media during use, the magnetic recording head comprising:
a main pole including a first main pole piece and a second main pole piece, the first main pole piece including pole tip occupying a portion of the ABS and a back edge distal from the ABS, the second main pole piece having a front surface, each of the first main pole piece and the second main pole piece being flat; at least one auxiliary pole having a front recessed from the ABS, the at least one auxiliary pole being magnetically coupled with the main pole; a nonmagnetic spacer between the back edge of the first main pole piece and the front surface of the second main pole piece; and at least one coil for energizing the main pole.
