ABSTRACT:
A process for manufacturing a magnetic recording medium comprising a composite film of an organic polymer and a ferromagnetic substance deposited on a non-magnetic support using a multicomponent simultaneous vapor deposition process. An incident beam of the organic polymer is irradiated on the support at an incident angle in the range of 60.degree.<.psi..sub.1 .ltoreq.90.degree. C. while an incident beam of the ferromagnetic substance is irradiated thereon so as not to overlap the incident beam of the organinc polymer and the incident direction of the magnetic substance in relation to the incident direction of the organic polymer is selectively set to form a high density magnetic recording medium having an improved magnetic property and having a magnetic anisotropy in a direction either perpendicular to or parallel to the surface of the magnetic film.
