Abstract
A film comprising fullerene molecules or their derivatives, preferably C.sub.60 or C.sub.70 fullerene molecules, is used as a lubricating film between two bearing surfaces. In a particular embodiment, a data recording disk file with the film deposited on the disk surface has improved properties of static friction and wear resistance at the head-disk interface.
