Abstract
A method for etching a media is disclosed. A first magnetic layer comprising grains is deposited with a segregant such that a portion of the first segregant covers a top surface of the grains of the first magnetic layer and a second portion of the first segregant separates the grains of the first magnetic layer. The first segregant is etched to remove the portion of the first segregant that covers the top surface of the grains.
