    摘要： A magnetic record medium comprises(A) a nonmagnetic substrate,(B) a layer consisting essentially of a ferromagnetic metal on at least one side of the substrate,(C) a layer containing carbon on the layer of (B),(D) a layer comprising a primary or secondary organic amine containing at least one substituent having a fluorinated hydrocarbon group at the end of the substituent on the layer of (C), and(E) a layer comprising at least one lubricant having a plurality or fully fluorinated hydrocarbon group on one end of the molecule and a functional group selected from the group consisting of --OH, --SH, --COOH, --COSH and --CONH.sub.2 on the other end of the molecule on the layer of (D).The magnetic record medium of the present invention has a good endurance reliability and does not cause deterioration of such performances as the CSS durability, head adsorption and still life at high temperatures and high humidities, even when the surface property is improved considerably by decreasing the height of surface protrusions for the purpose of improving the recording density.

    摘要： A method of producing a magnetic recording medium comprises the steps of heating in vacuum a magnetic recording medium produced by forming a ferromagnetic metal-film-type recording medium onto a non-magnetic substrate and of forming, immediately after heating, a protective layer on the magnetic recording medium by a plasma CVD method. A production apparatus for carrying out this method comprises a feeding apparatus for feeding a magnetic recording medium with a ferromagnetic thin film formed on a non-magnetic substrate, a plasma CVD apparatus, disposed in the path of this feeding apparatus, for forming a protective layer, and a heating apparatus disposed just before this plasma CVD apparatus in the feeding path.

    摘要： A magnetic recording medium produced by treating a magnetic recording medium which comprises a non-magnetic substrate and a magnetic layer formed on said substrate in an atmosphere kept at a temperature of at least 50.degree. C., with applying a tension of 1 gf. or less per 10 mm width to said magnetic recording medium in a treating time which is in a range on or above a line having a slope of at least 5000 in terms of .DELTA.ln(L)/.DELTA.(1/T) and passing a point of 0.5 second at 100.degree. C., when ln(L) is Arrhenius plotted against an inverse of an absolute temperature T (1/T), which medium has suppressed change of magnetic properties with time and improved corrosion resistance.
