A method and system for manufacturing a perpendicular magnetic recording
head is disclosed. The method and system include providing a chemical
mechanical planarization (CMP) uniformity structure having an aperture
therein and forming a perpendicular magnetic recording pole within the
aperture. The CMP uniformity structure may include a CMP barrier layer.
The method and system further include fabricating an insulator after
formation of the perpendicular magnetic recording pole and performing a
CMP to remove a portion of the insulator, expose a portion of the
perpendicular magnetic recording pole and planarize an exposed surface of
the perpendicular magnetic recording head.
