Sulfonamides useful as lubricants in magnetic recording media (Sulfonamides useful as lubricants in magnetic recording media)

摘要

The present invention relates to a substrate, a magnetic recording lamina, and a magnetic recording medium comprising at least one sulfonamide present in an amount sufficient to provide the desired tribological properties. Methods of lubrication of magnetic recording media include applying one or more sulfonamides to the surface of the magnetic recording medium or introducing one or more sulfonamides into the lamina of the magnetic recording medium.
