System for providing a perpendicular magnetic recording transducer using a split seed layer

摘要

A magnetic recording transducer comprises a main pole having a bottom, a top wider than the bottom, and a top bevel. The transducer further comprises a nonmagnetic gap covering the main pole, a portion of the nonmagnetic gap residing on the top of the main pole, a first seed layer, at least a portion of the first seed layer covering the portion of the nonmagnetic gap on top of the main pole, a second seed layer residing on the first seed layer, and a wrap-around shield on the second seed layer.

1. A magnetic recording transducer comprising:
a main pole having a bottom, a top wider than the bottom, and a top bevel; a nonmagnetic gap covering the main pole, a portion of the nonmagnetic gap residing on the top bevel of the main pole, the portion of the nonmagnetic gap having a substantially constant and being within one nanometer of a target thickness; a first seed layer, at least a portion of the first seed layer covering the portion of the nonmagnetic gap on top of the main pole; a second seed layer residing on the first seed layer; and a wrap-around shield on the second seed layer.
