Abstract
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.
Claims5
A lubricant layer which comprises a host-guest complex formed by a host compound which is a multidentate ligand having a function to reversibly trap a metal ion or an organic ion by electrostatic interaction and a guest compound, said host compound being coated on a solid surface.
