  • Thin film TiSixNy protective layer
    Patent number: 6586070
    Abstract: A overcoat layer of TiSixNy for use on a magnetic thin film disk is disclosed. The overcoat of the invention has high hardness, provides corrosion protection and has low surface energy which reduces contaminant attraction. The TiSixNy film is conductive and, therefore, reduces the deleterious effects of tribocharging.
