ABSTRACT:
A magnetic recording medium is described, comprising a support having provided thereon a thin magnetic metal vapor deposition film, said film being provided by evaporating a magnetic metal material from an evaporation source to generate a vapor flow and directing the vapor flow to contact a moving support at an inclined angle, and having a curved and inclined column structure formed by continuously altering the incident angle of said vapor flow on the moving support from a high degree (.theta..sub.max) to a low degree (.theta..sub.min), and a non-magnetic metal vapor deposition film provided on the magnetic metal film, said non-magnetic metal film being provided by continuously altering the incident angle of vapor flow of the non-magnetic metal material to the moving support on which the magnetic metal film is formed between a high degree (.theta..sub.max') and a low degree (.theta..sub.min').
