Abstract: A magnetic media has a substrate with an underlayer and a seed layer on the underlayer. The seed layer has a non-continuous metallic layer with a cubed crystalline lattice that is 001 textured, and has a lattice mismatch within 15% of a crystalline lattice structure of FePt with a metallic additive. This structure defines nucleation sites with an established epitaxial interface.

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.

Abstract: This invention provides a magnetic recording medium excellent in terms of corrosion resistance. The magnetic recording medium comprises a magnetic recording layer, a protective layer and a lubricant layer provided on a nonmagnetic substrate, and the lubricant layer comprises a compound having a heterocyclic ring.
