Zusammenfassung:Magnetic recording media having a protective carbon overcoat adapted to protect the magnetic recording layer from surface contact events and corrosion. The carbon overcoat includes at least two layers. A first layer is adapted to protect the magnetic recording layer from surface contact events and corrosion. The second layer is disposed on the first layer and is adapted to enhance the bonding of a lubricant to the carbon overcoat and to minimize head degradation. The magnetic recording media of the present invention advantageously enables the use of thin carbon overcoats, enhancing areal density, while maintaining good tribological properties.
