摘要： A magnetic recording medium having a thin magnetic film on a non-magnetic support base is disclosed. A layer of a compound which contains at least two isocyanate groups is formed in connection with the medium, and may be formed on either the surface of the metal film or the surface of the base opposite the metal film, or both. The resulting medium has excellent running properties, wear resistance and electro-to-magnetic conversion characteristics which are maintained after repeated use. The medium is formed by providing a non-magnetic support base surface and coating that surface with a thin magnetic metal film by use of a process such as vapor deposition. A solution of a compound containing at least two isocyanate groups is then applied to the medium within a solvent after which a heat treatment is carried out, thus forming the layer of compound containing the isocyanate groups.
