The bevel angle of the write pole for a perpendicular magnetic recording write head affects the performance of the write head. By forming reinforcement layer on the polymeric underlayer mask to enhance the mask durability during ion mill and tapering the polymeric underlayer above the non-magnetic mill mask layer using oxygen and nitrogen based reactive ion etch process, the bevel angle of the magnetic write pole can be increased greatly to meet the demands of the next and future generations of magnetic recording write heads."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High bevel angle magnetic writer pole fabrication process","description":"Methods of making write poles for perpendicular magnetic recording write heads.
