摘要： An energy assisted magnetic recording head comprises a slider having a leading edge, a trailing edge, and an air bearing surface (ABS), and a near field transducer (NFT) disposed in the slider and having a distal end proximate the ABS. The distal end is recessed from the ABS when no optical power is applied to the NFT, and is co-planar with the ABS when a predetermined amount of optical power is applied to the NFT. A portion of the slider surrounding the distal end forms a concave surface having a continuously varying slope when no optical power is applied to the NFT, and a flat surface coplanar with the ABS and the distal end when the predetermined amount of optical power is applied to the NFT. Applying optical power comprises coupling light into a waveguide formed in the head and directing the coupled light to the NFT via the waveguide.
