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 EAMR transducer includes an NFT for focusing the energy onto the media. A sacrificial layer is deposited on the NFT and a mask having an aperture provided on the sacrificial layer. A portion of the sacrificial layer exposed by the aperture is removed to form a trench above the NFT. A heat sink is then provided. At least part of the heat sink resides in the trench. The heat sink is thermally coupled to the NFT. Optical material(s) are provided around the heat sink. A write pole configured to write to a region of the media is also provided. The write pole is thermally coupled with the top of the heat sink. Coil(s) for energizing the write pole are also provided.
