The transducer includes a magnetic writer pole having a pole tip facing an air bearing surface (ABS). The pole tip includes a pole tip face having a leading edge, a trailing edge, a first side wall, and a second side wall. The first side wall includes a first side wall section adjoining the leading edge and a second side wall section adjoining the trailing edge. The first side wall section is at a first angle measured from a perpendicular center line dividing the trailing edge. The second side wall section is at a second angle measured from a perpendicular center line dividing the trailing edge. The second angle is greater than three degrees. The first angle is greater than the second angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perpendicular magnetic recording writer pole with leading and trailing bevel side wall angles at air bearing surface","description":"A perpendicular magnetic recording transducer with leading and trailing bevel side wall angles at air bearing surface for use in a data storage device is provided.
