Abstract
A method and system provide a shingle magnetic write transducer. The transducer has an air-bearing surface (ABS) and includes a main pole and at least one coil. The coil(s) are configured to energize the main pole. The main pole includes a leading surface, a trailing surface, and a plurality of sides between the leading surface and the trailing surface. At least one of the plurality of sides form a sidewall angle with a down track direction. The sidewall angle is less than thirteen degrees and is at least zero degrees. In some aspects, the sidewall angle is less than a maximum skew angle for the data storage system.
