Abstract: A data writer may be configured with a write pole that has one or more sidewalls continuously extending from an air bearing surface. A write pole sidewall can have a plurality of different wall angles. A portion of a write pole sidewall contacting the air bearing surface can have a first wall angle with respect to a trailing edge of the write pole, parallel to the air bearing surface. A second portion of the write pole sidewall can be half or less of the first wall angle. A third portion of the write pole sidewall can be smaller than the second wall angle.
