Abstract: A method for manufacturing a magnetic media for magnetic data recording that greatly reduces the time required to manufacture the magnetic media. After constructing the magnetic disk with the desired magnetic media layer, a protective overcoat is deposited on the disk. The disk is then exposed to ozone in order to speed the rate of oxidation of the protective overcoat and thereby reduce the time needed to treat the overcoat. After exposing the overcoat to an ozone a lubrication layer can be applied. This process reduces the time necessary to cure the overcoat from a time of about 24 hours to a time range of 10 seconds to 30 minutes.

Abstract: A magnetic media for magnetic data recording having a plurality of magnetic grains protected by thin layers of graphitic carbon. The layers of graphitic carbon are formed in a manner similar to onion skins on an onion and can be constructed as single monatomic layers of carbon. The thin layers of graphitic carbon can be formed as layers of graphene or as fullerenes that either cover or partially encapsulate the magnetic gains. The layers of graphitic carbon provide excellent protection against corrosion and wear and greatly reduce magnetic spacing for improved magnetic performance.
