PURPOSE:To improve reliability with narrow tracks and short wavelength by disposing a substantially single-layered top coat layer consisting of a discontinuous diamond-like hard carbon film and discontinuous lubricating film on a thin ferromagnetic metallic film. CONSTITUTION:The substantially single-layered top coat layer 9 is disposed of the discontinuous diamond-like hard carbon film 10 and the discontinuous lubricating film 11 on the thin ferromagnetic metallic film 8. The lubricating agent is, therefore, hardly removable by constituting members of a magnetic head and running system and the repetitive uses in the stable running state are permitted, unlike in the case in which said film is laminated by the diamond- like hard carbon film and the lubricating film. In addition, the direct contact with the magnetic recording layer is prevented. The satisfactorily high reliability is thus assured in spite of the high-speed sliding contact with a magnetic head. |
