Process for lubricating magnetic disks, and to magnetic disks.

摘要

A process for lubricating a magnetic disk consists of applying a polymeric lubricant having a functional terminal group to a magnetic disk, heating the lubricant so that the functional group covalently bonds to surface polymers and/or metal oxides of the magnetic disk, and then either removing the unreacted lubricant with a solvent and then contacting the disk with a non-functionalised lubricant or reacting the unreacted lubricant with an aziridine or epoxide compound.
