    摘要: A magnetic head includes: a pole layer including a track width defining portion and a wide portion; and an accommodation layer disposed on a bottom forming layer and having a groove that accommodates the pole layer. The groove includes a first portion for accommodating at least part of the track width defining portion, and a second portion for accommodating at least part of the wide portion. A manufacturing method for the magnetic head includes the steps of: forming a groove defining layer on a nonmagnetic layer that is intended to later become the accommodation layer; forming a mask that covers an area of the nonmagnetic layer where to form the first portion of the groove; etching the nonmagnetic layer so that the second portion of the groove is formed in the nonmagnetic layer; removing the mask; and taper-etching the nonmagnetic layer so that the first portion of the groove is formed in the nonmagnetic layer and the groove is thereby completed.

    摘要: A perpendicular magnetic recording (PMR) head is fabricated with main pole and a trailing edge shield antiferromagnetically coupled across a write gap by either having the write gap layer formed as a synthetic antiferromagnetic tri-layer (SAF) or formed as a monolithic layer of antiferromagnetic material. The coupling improves the write performance of the writer by enhancing the perpendicular component of the write field and its gradient. Methods of fabricating the writer are provided.
