Email this article Formulating Heat Transfer Across The Head-Media Interface- HAMR
Abstract
All past thermal demonstrating on warmth trade between hard disk drive (HDD) head and media regarded media as a warmth sink with uniform encompassing temperature. However in warmth helped attractive recording (HAMR) framework, the media temperature is no more uniform and the temperature at the problem area focus can reach as high as 800 to 1000 K contingent upon recording layer's Curie temperature. In this paper, both media problem area and the air bearing stream are incorporated into detailing heat exchange over the head-media interface. Numerical results for a waveguide just slider and a slider with a metallic close field transducer (NFT) are introduced to delineate the impact of HAMR media temperature.
