Abstract
A HAMR data storage device may include a magnetic media and a slider comprising: a main pole, a waveguide, and a near-field transducer (NFT) situated between the main pole and the waveguide, wherein an air-bearing surface (ABS) of the slider comprises a transparent overcoat layer situated over the main pole, the waveguide, and the NFT, and wherein the transparent overcoat layer has a particular thickness such that, during an operational phase of the HAMR data storage device, a gap between a media-facing surface of the transparent overcoat layer and the magnetic media is less than about 0.5 nm.
