▎ 摘　　要

NOVELTY - The method involves forming a graphene layer with an upper substrate. A heat releasing adhesive tape layer is matched with the graphene layer. A magnetic medium material layer is matched with the heat-releasing adhesive tape layer. A roller shaft is formed with the heat-releasing adhesive tape layer. A magnetic medium material layer is separated from the graphene layer and the heat-releasing adhesive tape layer. The substrate is copper substrate. Corrosion removing process is performed. USE - Magnetic storage device preparing method. ADVANTAGE - The method enables reducing flying height of magnetic head and increasing magnetic storage density and stability of disk. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a/an magnetic storage device preparing method. '(Drawing includes non-English language text)'
