A sputtering production assembly for producing a magnetic thin-film memory disk and a method of coating the memory disk is provided. The magnetic disk substrates are preliminarily abraded to provide a uniform series of physical circumferential texturing to encourage a circular anisotropic orientation of crystal growth during the subsequent sputtering steps. A nucleating layer is deposited under controlled conditions, and subsequently a thin-film magnetic layer is deposit with a circular anisotropic orientation of crystal growth. Finaly, a thin-film protective coating is disposed on the magnetic layer.
