A method and system provide a magnetic transducer having an air-bearing surface (ABS) and an intermediate layer. A trench having a shape and location corresponding to a main pole is formed in the intermediate layer. The main pole is provided. At least a portion of the main pole is in the trench. Providing the main pole further includes vacuum depositing a first main pole material layer. The first main pole material layer is thin enough to preclude filling of the trench. The first main pole material layer is then ion beam etched. A second main pole layer is vacuum deposited on the first main pole layer. The second main pole material layer is also thin enough to preclude filling of the trench. An additional main pole layer is also deposited.
