Abstract :
A coarse-grained molecular dynamics simulation of the spreading of monolayer lubricant films on magnetic disks is presented. The simulated diffusion coefficient for various coverages of the bonded molecules was in good agreement with that obtained by an experiment using the half-dip method. The simulated relation between the coverage and bonding ratio was also in good agreement with the experimental one
