▎ 摘　　要

NOVELTY - The method involves generating a graphene layer, and generating a magnetic medium material layer on the graphene layer. A substrate layer is formed on the magnetic medium material layer, where the substrate is silicon substrate or silicon dioxide substrate. The graphene layer is transferred to an upper supporting layer. The supporting layer is peeled off after the substrate layer is formed in the magnetic medium material layer. A lubricating layer is formed on the graphene layer. USE - Magnetic storage device preparation method. ADVANTAGE - The method enables using a graphene magnetic storage device to replace the original DLC, effectively reducing the flying height in the magnetic head and the magnetic disk storage device and increasing magnetic storage density. The method enables tightly combining graphene layer and magnetic medium material layer to increase the stability of the graphene layer and magnetic medium material layer. The method enables making the graphene layer with better absorbing effect, reducing the diffusion influence to magnetic medium material layer and increasing stability of disk.
