Abstract
A method provides an EAMR transducer. The EAMR transducer is coupled with a laser and has an ABS configured to reside in proximity to a media during use. The method includes providing an NFT using an NFT mask. The NFT resides proximate to the ABS and focuses the laser energy onto the media. A portion of the NFT mask is removed, forming a heat sink mask covering part of the NFT. Optical material(s) are deposited, covering the heat sink mask and the NFT. The heat sink mask is removed, providing an aperture in the optical material(s). A heat sink corresponding to the aperture is provided. The heat sink bottom is thermally coupled with the NFT. A write pole for writing to the media and coil(s) for energizing the write pole are provided. The write pole has a bottom surface thermally coupled with the top surface of the heat sink.
