摘要： A method for manufacturing a write pole for perpendicular magnetic recording for accurately defining a side shield throat height and write pole flare point. The magnetic structure includes a write pole portion and first and second side shield portions. The side shields portions are magnetically connected with the write pole portion in a region in front of an intended air bearing surface plane (e.g. in the direction from which lapping will progress). The side shields portions are each separated from the write pole portion in a region behind the intended air bearing surface plane by notches that terminate at a desired location relative to the intended air bearing surface plane and which open up in a region behind the intended air bearing surface plane.
