摘要：
A main pole of a perpendicular magnetic recording write head is disclosed with a non-rectangular shape at the air bearing surface and a rectangular shape behind the air bearing surface. The main pole transitions from the non-rectangular shape to a rectangular shape at a distance of 10 nm to 100 nm behind the air bearing surface. The main pole includes leading and trailing beveled surfaces that extend from the non-rectangular shape of the pole at the air bearing surface toward the rectangular shape transition.
