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.

摘要： PROBLEM TO BE SOLVED: To make it possible to obviate the occurrence of peeling of multilayered back coating layers even after long-term preservation or under a severe use environment and to maintain the characteristics of a medium by forming the magnetic recording medium having a magnetic recording layer on one surface of a nonmagnetic base and the multilayered back coating layers on the other surface, forming the nonmagnetic base side of the multilayered back coating layers of the applied back coating layers composed mainly of nonmagnetic particles and an org. binder and forming the front surface side of thin-film back coating layers by vacuum thin-film formation. SOLUTION: The magnetic recording layer 2 and a top coating layer 3 are formed on one surface of the nonmagnetic base 1. The multilayered back coating layers 40 are formed on the rear surface of the nonmagnetic base 1. The multilayered back coating layers 40 consist of the applied back coating layer 41 on the nonmagnetic base 1 side and the thin-film back coating layer 42 formed thereon and the thin-film back coating layer 42 is formed to >=3nm in its film thickness to prevent the direct exposure of the applied back coating layer 41 on the surface. The preservation life of the medium is improved by the multilayered back coating layers.
