To further increase recording density of disk storage drives, laser-assisted magnetic recording can solve the fundamental programs of thermal fluctuation and is regarded as the keytechnology for achieving 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. Because they are heated to high temperature with laser beams. In this study, we focused on the thermal stability of the three lubricant film materials in laser-assisted magnetic recording. In other words, the behavior of lubricant film under the laser heating was investigated and discussed experimentally. As a result, it was found that the effects of lubricant materials as well as the laser irradiation conditions on the lubricant film depletion were clantied.
