This paper presents a numerical investigation of heat transfer and lubricant depletion on the hard disk in a heat-assisted magnetic recording (HAMR) system. The heat is induced by a laser pulse shooting down from a slider flying over the disk coated with a thin layer of lubricant. The main mechanism...
