THERMALLY STABLE AU ALLOYS AS HEAT DIFFUSION AND PLASMONIC UNDERLAYER FOR HEAT-ASSISTED MAGNETIC RECORDING (HAMR) MEDIA

摘要

PROBLEM TO BE SOLVED: To provide thermally stable Au alloys as a heat diffusion and plasmonic underlayer for heat-assisted magnetic recording (HAMR) media.;SOLUTION: According to one embodiment, a magnetic medium includes a plasmonic underlayer having an Au alloy, and a magnetic recording layer atop the plasmonic underlayer. The Au alloy includes one or more alloying components that are substantially immiscible in Au. According to another embodiment, a magnetic medium includes a multilayered plasmonic underlayer, and a magnetic recording layer atop the multilayered plasmonic underlayer.;COPYRIGHT: (C)2015,JPO&INPIT
