  • Magnetic thin film media with chromium capping layer
    Patent number: 6641932
    Abstract: A flash chromium capping layer is deposited on a magnetic layer for improved corrosion resistance, reduced poisoning due to the absence of a protective overcoat or presence of discontinuities in a protective overcoat, and for reduced media noise do to inter-granular exchange coupling. Embodiments include depositing a flash chromium layer having a thickness up to about 10 Å on an upper magnetic layer and depositing an overlying lubricant topcoat. An optional protective overcoat, such as a carbon-containing protective overcoat, can also be deposited on the chromium capping layer. The chromium capping layer forms a protective oxide coating where exposed, as due to the absence of or at discontinuities in the protective overcoat.
