The tribological behavior of perfluoropolyether (PFPE) films attached to perpendicular recording magnetic disks coated with diamondlike carbon (DLC) was studied in lateral vibration wear tests using lateral modulus friction force microscopy (LM-FFM). The viscoelastic and frictional properties of these PFPE films without heat cure were improved due to the lubricant supply by tip sliding. However, the PFPE films were easily removed with increasing load and lateral vibration amplitude following heat treatment since the free lubricants on the films solidified resulting in the lost of fluidity.
