Abstract
In the manufacture of a thin film metal alloy or metal oxide magnetic recording disk, a fluoroether lubricant is bonded to the carbon or hydrogenated carbon overcoat of the disk. The lubricant is applied to the carbon overcoat by dipping the disk in a solution of the lubricant. The lubricated disk is then exposed to the plasma of an inert gas, such as nitrogen. The resulting disk contains a layer of lubricant which is bonded to the disk surface so as to be resistant to spin-off and which has a relatively uniform thickness so as to substantially eliminate the problems of stiction during the operation of the disk file.
