A method provides a magnetic transducer having an air-bearing surface (ABS) location. An intermediate layer having a substantially flat bottom surface is provided. A trench is formed in the intermediate layer. The trench is wider in yoke region than in the pole tip region. The trench has a first depth in the yoke region and a second depth less than the first depth in the pole tip region. A portion of the intermediate layer is at the bottom of the trench at the ABS location. A nonmagnetic layer is provided. The nonmagnetic layer fills part of the trench in the pole tip region such that the trench has a third depth less than the second depth at the ABS location. A main pole is provided. The main pole has a leading bevel adjacent to nonmagnetic layer in the portion of the pole tip region of the trench.
