All previous thermal modeling on heat exchange between HDD head and media treated media as a heat sink with uniform ambient temperature. However in HAMR system, the media temperature is no longer uniform and the temperature at the hot spot center can reach as high as 800 to 1000K. In this paper, both media hot spot and the air bearing flow are included in formulating heat transfer across the head-media interface. Numerical results for a waveguide only slider and a slider with metallic near-field transducer (NFT) are presented to illustrate the effect of HAMR media temperature.
