Abstract: Carbon is sputter-deposited as a protective overcoat on the coating of a magnetic recording disk of the type in which the coating includes magnetic particles dispersed in an organic binder. The carbon film exhibits excellent durability and lubricity, thereby eliminating the need to incorporate alumina or other load-bearing particles into the magnetic coating, and eliminating the need for a liquid lubricant on the disk surface.

Abstract: A thin film metal alloy magnetic recording disk has a protective nitrogen-containing carbon overcoat which is thinner and which exhibits better wear resistance, corrosion resistance, and hardness than conventional carbon overcoats without nitrogen. The nitrogen present in the disk overcoat substantially reduces the film stress. Because of the low stress of the overcoat film there is significantly less likelihood that the overcoat will delaminate, buckle, or otherwise wear away from the underlying magnetic layer during operation of the disk file. This allows for significantly reduced overcoat thickness, thus reducing the head-disk spacing in the disk file. The overcoat, even though significantly thinner than prior art carbon overcoats, exhibits better wear and corrosion resistance than carbon overcoats without nitrogen. In addition, when the carbon overcoat contains hydrogen, the presence of the nitrogen increases the hardness of the film if present in a specific amount dependent on the amount of hydrogen present.

Abstract: PROCESS FOR BONDING A DURABLE LOW SURFACE ENERGY COATING This invention is concerned with a process for bonding a durable low surface energy coating to a metal or oxide surface. The metal or oxide surface is first treated with an alkali and then in the dry state with a material containing a fluorinated alkyl group linked by an ether linkage to an alkyl silane group. The invention can be used, for example, as friction reducing, inert coatings for ink jet nozzles, magnetic disks and the like.
