Abstract
A method and system provide a magnetic transducer that includes an underlayer and a first nonmagnetic layer on the underlayer. The method and system include providing a first trench in the first nonmagnetic layer. The first trench has at least one edge corresponding to at least one side shield. The method and system also include providing a second nonmagnetic layer in the first trench and providing a second trench in the second nonmagnetic layer. The method and system include providing the main pole. At least part of the main pole resides in the second trench. The method and system further include removing at least a portion of the second nonmagnetic layer between the edge(s) and the main pole. The method and system also provide the side shield(s) in the first trench. The side shield(s) extend from at least an air-bearing surface location to not further than a coil front location.
