Abstract

The thickness of a lubricant is 1 to 2 nm for a current magnetic disk, and this means that the lubricant is a monolayer or sub-monolayer. The two-layer model has been widely accepted for rather thick lubricants. In that model, a lubricant film consists of the first layer bonded to the disk and the mobile layer on the bonded layer. However, the conventional two layer model is not applicable to a current monolayer lubricant film for a magnetic disk. In this paper, based on the investigation of the molecular conformation and spreading characteristics, we clarify the diffusive motion of mobile molecules in order to build a tribological model for a monolayer lubricant.
