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.

The method and system for providing a magnetic element are disclosed. The method and system include providing a magnetic element stack that includes a plurality of layers and depositing a stop layer on the magnetic element stack. The method and system also include providing a dielectric antireflective coating (DARC) layer on the stop layer, forming a single layer mask for defining the magnetic element on a portion of the DARC layer, and removing a remaining portion of the DARC layer not covered by the single layer mask. The portion of the DARC layer covers a portion of the stop layer. The method further includes removing a remaining portion of the stop layer and defining the magnetic element using at least the portion of stop layer as a mask.
