摘要:
A method provides an EAMR transducer. A sacrificial post is provided on an NFT distal from the ABS. This post has an edge proximate and substantially parallel to the ABS. A sacrificial mask is provided on the NFT between the post and the ABS. Optical material(s) are provided. The post is between the optical material(s) and the ABS. The post is removed. A heat sink post corresponding to the post is provided. The heat sink post has a bottom thermally coupled with the NFT and an edge proximate and substantially parallel to the ABS. Part of the heat sink post is removed, forming a heat sink having a top surface at an acute angle from the ABS. Nonmagnetic material(s) are provided on the optical material(s). A pole having a bottom surface thermally coupled with the heat sink and coil(s) are provided.
