NOVELTY - A magnetic disk comprises a recording layer; and a layer of graphene formed above the recording layer. USE - In a computer; in magnetic data storage system such as disk drive system. ADVANTAGE - The magnetic disk comprises the metallic seed layer/graphene combination offers the additional advantage that the dual layers can provide corrosion protection even if the graphene layer is not fully contiguous over small length scales. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a magnetic device comprising a transducer; a nucleation layer formed above the transducer; and a layer of graphene formed on the nucleation layer; (2) forming (M1) a layer of graphene involving forming a nucleation layer above a magnetic layer of a magnetic disk or magnetic device; and forming a layer of graphene on the nucleation layer; (3) forming (M2) a layer of graphene on a SiC layer involving depositing SiC above a magnetic layer of a magnetic disk or magnetic device, the SiC being equivalent to several monolayer thick; surface heating the SiC to selectively evaporate some of the silicon (Si) from the SiC for forming a layer of graphene on a SiC layer; and (4) removing the polymer material involving: forming graphene on a sacrificial layer; transferring the graphene onto a polymer carrier; transferring the graphene and polymer carrier onto a magnetic disk or magnetic device; and removing the polymer material.
