摘要： PROBLEM TO BE SOLVED: To attain downsizing of a metal thin film type magnetic recording medium without reducing the conventional mechanical strength thereof and to prevent the generation of thermal distortion.
SOLUTION: A reinforcing layer 2 is deposited on the surface opposite to a magnetic layer 4 of a non-magnetic substrate 1 of the metal thin film type magnetic recording medium 100. Since the non-magnetic substrate having relatively low rigidity is interposed between the magnetic layer and the reinforcing layer both having relatively high rigidity, the distribution of rigidity is made uniform and whole mechanical strength is further enhanced. Since the non- magnetic substrate adheres closely to a cooling member by the electric charge the reinforcing layer has and the heat generated when the vacuum thin film is deposited is satisfactorily transmitted to the cooling member and dissipated, generation of the thermal distortion of the non-magnetic substrate can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a metal thin film type magnetic recording medium which realizes improvement in the productivity and/or a smaller size (thin films) than a conventional medium.
SOLUTION: A nonmagnetic metal layer 2 is formed between a nonmagnetic supporting body 1 and a metal magnetic layer 3 of the metal thin film type magnetic recording medium 100. The metal layer increases the deposition rate of a protective film 4 to be formed on the outside of the metal magnetic layer and to improve the productivity of the recording medium. Thin films of the recording medium can be obtained by controlling the thickness of the metal layer in such a manner that the total thickness of the metal layer and the metal magnetic layer is smaller than the thickness of a conventional metal magnetic layer.
