Protective overcoating for magnetic recording discs and method for forming the same |
摘要 |
A protective overcoating is disclosed for a magnetic alloy thin-film recording disc that includes a magnetic alloy film formed on a disc-shaped substrate or coated substrate. The protective overcoating is formed by first sputtering onto the magnetic medium an interfacial layer of titanium, and then sputtering onto the titanium a layer of carbon. The sputtered carbon provides wear-resisting lubricity, while the titanium interface promotes the adhesion of the sputtered carbon to the magnetic medium of the recording disc.
