发明名称 MAGNETIC RECORDING HEAD
摘要 A magnetic recording head includes a first pole having multiple magnetic layers separated by multiple gap layers. The multiple magnetic layers make up a write pole which produces a first hard axis field and a first auxiliary pole that produces a first auxiliary field that opposes the first hard axis field resulting in a reduced net hard axis field. The write pole and the first auxiliary pole are separated by a first gap layer made of a material that is less magnetically conducting than the write pole and the first auxiliary pole. The write pole is located upstream from the first auxiliary pole relative to a perpendicular magnetic recording medium. A portion of the first auxiliary pole exists in a region between a surface of the perpendicular magnetic recording medium and five microns from a surface of the perpendicular magnetic recording medium.
