    摘要: A writer pole for perpendicular recording and a method of manufacturing the same are provided. The writer pole comprises a laminated structure of a first magnetic layer, a second magnetic layer, and a non-magnetic amorphous metal spacer layer disposed between the first and second magnetic layers. Additional ferromagnetic and non-magnetic layers can be added, in an alternating fashion, to produce other laminated structures. Forming a perpendicular writer element includes forming a first magnetic layer, forming a spacer layer on the first magnetic layer, and forming a second magnetic layer on the spacer layer. Forming the perpendicular writer element can further include trimming the writer pole.
