Molecular dynamics studies of lubricant depletion under moving laser heating: Effects of laser power and film thickness

“…It has been reported that the commercially used perfluoropolyether (PFPE) lubricants such as PFPE Zdol can be completely removed in less than 1000 laser shots [1]. Zhang et al [2] numerically studied the effects of laser power and laser spot size on the recorded mark width in HAMR. It was shown that the mark width increases with the laser power nonlinearly due to the Gaussian distribution of the laser intensity.…”
