摘要：
A graphene layer, used as an anti-corrosive protection medium for magnetic media, overcomes the existing problem of reducing the carbon overcoat layer thickness for magnetic media. Unlike the amorphous carbon that is currently used as an anti-corrosion layer, the impenetrability of graphene to all known gaseous substances enables full corrosion protection of the underlying magnetic medium with a layer of graphene that may be, for example, as thin as a single layer of graphene. The dry transfer of graphene onto magnetic recording disks is enabled, such that the resulting interface of the graphene with the magnetic layer is protested from contact with impurities.
