Laser-assisted magnetic recording is one of the novel technology for achieving a magnetic recording density of more than 1 Tb/in^2. In this technology, it is suggested that there is serious issues for the ultra-thin liquid lubricant films on the disk surfaces. This is because these films are heated to high temperature using laser beams. In this study, we focused on the local temperature on disk surface due to laser heating in laser-assisted magnetic recording. The local temperature increase was identified using the change of refractive index and absorption coefficient of the DLC film experimentally. In addition, the estimated temperature was compared with the computer simulation results and good agreement was obtained.
