PROBLEM TO BE SOLVED: To provide a magnetic recording medium, in which a rigid carbon film as an alkali metallic stopper layer for preventing the occurrence of defects on a magnetic film caused by the migration of the alkali metal from a glass substrate is provided with the satisfied tight adhesion strength with respect to the glass substrate and an Ni-P film. SOLUTION: The magnetic recording medium which is arranged by being successively laminated with the rigid carbon film on the glass substrate, Ni-P film, magnetic film, protective film and lubrication film, is constituted so that at least one layer is provided out of the 1st tight adhesive layer with Si as the main component arranged between the glass substrate and the rigid carbon film, or the 2nd tight adhesive layer with Ti as the main component arranged between the rigid carbon film and the Ni-P film.
