Beschreibung
Zusammenfassung:	A method for manufacturing a magnetic recording medium, which includes providing a substrate for the magnetic recording medium, electrically charging the substrate with a positive voltage, and then forming the thin film layers on the substrate. The thin film layers includes at least a metallic underlayer, a magnetic recording layer, a protective layer composed of at least carbon, and a lubricant layer, formed in this order on the substrate. The method enables manufacture of a magnetic recording medium that exhibits high reliability and good read/write performance.
