Abstract
A hydrogenated carbon film for magnetic thin film recording media is manufactured by alternating current magnetron sputtering in an atmosphere containing argon and a hydrocarbon gas. Targets mounted side-by-side cyclically sputter and discharge charge buildup according to an alternating current. Shielding between the targets directs electrons toward the anode at a given time.
