Abstract

The diffusive motion of molecules of monolayer perfluoropolyether lubricants on magnetic disks have been clarified by investigating spreading characteristics. A model for the diffusive motion of the mobile molecule is presented. The diffusive motion can be explained by a modified reptation theory. The mobile molecule makes a snake-like diffusive motion through the bonded ones. These results are useful for building a tribological model of a monolayer lubricant on a magnetic disk.
