Abstract
A method and system for fabricating an energy assisted magnetic recording (EAMR) transducer is described. The EAMR transducer has an air-bearing surface (ABS) and a waveguide. The method includes providing a planarized near field transducer (NFT) for the waveguide and forming a sloped surface on the planarized NFT. The sloped surface has a front edge separated from the ABS by a distance. The method and system also include providing a write pole on the sloped surface.
