ABSTRACT:
A magnetic recording medium, consisting essentially of a polymeric, web-like substrate and a coherent thin layer of a ferromagnetic material, is produced in a chamber under reduced pressure by depositing a vapor jet of the ferromagnetic material onto the moving substrate surface guided over a cylindrical drum, by a process in which the axis of the cooling element is inclined relative to the plane of the evaporator unit.
