| abstract | PURPOSE: To decrease strains and to improve toughness by allowing metal atoms to coexist in a protective film. n CONSTITUTION: A Cr underlying layer 3 and a magnetic film 4 consisting of a Co-Ni alloy are formed successively by sputtering on a substrate 2 for disks formed with an Ni-P plating film 2 at 10μm thickness. A composite type hydrogenated carbon film 5 contg. Fe is formed as the protective film thereon at 40nm thickness by a chemical vapor deposition method utilizing the plasma reaction of a gaseous mixture rf formed by mixing ferrocene at various ratios into the glow discharge space of methane. Further, a fluorine lubricant 6 is applied at 5nm thickness thereon. Strains are thus relieved without losing the wear resistance and corrosion resistance and the toughness is improved. n COPYRIGHT: (C)1991,JPO&Japio |
