摘要：
A magnetic write apparatus has a media-facing surface (MFS) and includes a main pole, an auxiliary pole, a magnetic separation layer and coil(s). The auxiliary pole is adjacent to the main pole and has an auxiliary pole front surface recessed from the MFS by a first distance. The first distance is nonzero. The magnetic separation layer has a front surface facing the MFS and a back surface opposite to the front surface. The back surface is closer to the MFS than the first distance. The front surface is recessed from the MFS by a second distance that is nonzero. The coil(s) energize the main pole.
