An improved magnetic medium has a metal or semiconductor surface in which the surface of the magnetic medium has an approximate monolayer of fullerene molecules 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, in particular heads with magnetic transducers and magnetic or optical-magnetic discs. 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.
A disc drive data storage system comprising a magnetic material and a means for protecting the surface of the magnetic material.
A disc drive data storage system comprising a magnetic material having a coating surface of a material selected from the group consisting of metals, semiconductors and mixtures thereof, wherein the coating surface has an approximate monolayer of fullerene molecules bonded to the coating surface with a bond strength greater than fullerene—fullerene intermolecular bond strength.
A method for protecting a surface of a magnetic material in a disc drive data storage system, the method comprising depositing an approximate monolayer of fullerene molecules on the surface of the magnetic material wherein the surface comprises a material selected from the group consisting of metals, semiconductors and combinations thereof and wherein the surface is substantially free of contaminants.
A method for protecting a surface of a magnetic material in a disc drive data storage system, the method comprising depositing fullerene molecules on a surface of the magnetic material under ultrahigh vacuum with a pressure no more than about 1×10−7 torr.
