Abstract

A novel lubricant with good thermal stability (T_d=328degC) is developed for the application of heat-assisted magnetic recording (HAMR) media to achieve the areal density of 1 Tb/in² and beyond. Compared to currently-used commercial lubricants, the newly developed lubricant film can resist the laser irradiation without damage while Z-dol film is completely depleted under the same experimental conditions. Frictional coefficient and dewetting behavior are also superior to the candidate for HAMR media protection
