ULTRATHIN PROTECTIVE OVERCOATS FOR MAGNETIC MATERIALS

摘要

An improved magnetic medium (100, 110) has a metal or semiconductor surface (102, 114) in which the surface of the magnetic medium has an approximate monolayer of fullerene molecules (104, 116) bonded to the metal or semiconductor surface. The bond strength between the fullerene molecules and the surface is stronger than the fullerene-fullerene intermolecular bond strength. The magnetic media can be used in the production of components for data storage system (200), in particular heads with magnetic transducers (218, 250) and magnetic or optical-magnetic discs (208, 300, 326). In methods for forming the fullerene coatings, an approximate monolayer of fullerene molecules are deposited on a metal or semiconductor surface substantially free of contaminants.
