Heat assisted magnetic recording is an advanced technology which can enable storage density increase in next generation hard disk drive. These drives are implemental in server (cloud) storage and the storage of large projects such as the Event Horizon Telescope which recently captured images of a black hole. The data is written on the magnetic surface by means of laser heating. The coercivity of magnetic medium is reduced by heating surface and within heating period data is written on disk. During the heating process, lubricant present on the disk might evaporate because of high temperature of laser and can accumulate on the slider which may reflow back to the dick after the end of heating process. This variation in the volume of lubricant on disk causes lubricant thickness variation, which may reduce efficiency of the process. Lubricant distribution and temperature distribution on disk & slider surface are evaluated with the help of lubricant film simulation.
