Abstract:
1. A method for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser for providing energy and having an air-bearing surface (ABS) configured to reside in proximity to a media during use, the EAMR transducer including a near field transducer (NFT) proximate to the ABS for focusing the energy onto the region of the media, the method comprising: providing a sacrificial post on a first portion of the NFT distal from the ABS, the sacrificial post having a first edge proximate and substantially parallel to the ABS; providing a sacrificial mask on a second portion of the NFT between the sacrificial post and the ABS; providing at least one optical material adjacent to the sacrificial post, the sacrificial post residing between the at least one optical material and the ABS; removing the sacrificial post; providing a heat sink post corresponding to the sacrificial post, the heat sink post having a bottom and the first edge proximate and substantially parallel to the ABS, the bottom of the heat sink post being thermally coupled with the NFT; removing a portion of at least the heat sink post to provide a heat sink having a bottom thermally coupled with the NFT and a top surface at an angle with respect to the ABS, the angle being greater than zero and less than ninety degrees; providing at least one nonmagnetic material on at least the at least one optical material, the at least one nonmagnetic material having a top surface at a second angle with respect to the ABS, providing a write pole configured to write to a region of the media, the write pole having a bottom surface, a portion of the bottom surface thermally coupled with the top surface of the heat sink; and providing at least one coil for energizing the write pole.
