Diamond-like carbon (DLC) is presently used as a protective coating on disks, heads and sliders used in magnetic storage technology [1]. The rapidly increasing storage density of magnetic thin film media will soon require carbon overcoats of only 2 nm thickness. The carbon overcoats are presently made by magnetron sputtering, but method is likely to be unsuitable for the ultra-thin coatings required in future. This paper describes methods to produce thinner coatings, and ways to characterise them.
