发明名称 PMR WRITER AND METHOD OF FABRICATION
摘要 Embodiments of the invention provide a magnetic recording head including a write pole having increasing magnetic moment from a leading edge of the write pole to a trailing edge of the write pole, and methods for manufacturing the same. The write pole may be formed with a plurality of different magnetic material layers having different magnetic moments. A first magnetic layer may be formed with a first magnetic material adjacent a leading edge of the write pole. A second magnetic layer having a greater moment may be formed on the first magnetic layer, thereby increasing the magnetic moment from the leading edge of the write pole to the trailing edge of the write pole.
