A film comprising fullerene molecules or their derivatives, preferably C(60) or C(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.
