Surface having a coating of a host multidentate ligand and a reversibly trapped lubricant

摘要

The lubricant layer according to the present invention is used in a thin film magnetic recording medium in which a solid surface sliding at a high speed is required to retain its lubricating performance and abrasion resistance for a long period of time, comprising a host-guest complex composed of a lubricant molecule as a guest molecule and a multidentate ligand as a host compound to form the complex with the guest molecule.
