Abstract

PURPOSE:To effectively prevent the thermal deformation of substrate, by inserting the ground film layer of silver or aluminum between the substrate and the ferromagnetic metal thin film layer. CONSTITUTION:On the substrate surface made of macromolecular moldingmaterial, the ground film layer made of silver or aluminum is formed with vapor deposition in about >=2,000Angstrom thickness. The specified ferromagnetic metal thin film layer is formed on this ground film layer with vapor deposition. By this method, the radiation heat from the vapor generation source produced at the vapor deposition of the feeromagnetic thin film layer is efficiently reflected at the ground film layer made of silver or aluminum, then it is not absorbed in the substrate. Accordingly, the magnetic recording medium almost without thermal deformation can be obtained.
