ABSTRACT:
A magnetic recording medium manufacturing device in which a flexible belt-shaped support is conveyed above a molten metal vaporizing source substantially at a constant speed while a magnetic film is formed on a surface of the support by vacuum deposition. The support is guided by transporting means such that the support is curved above the molten metal vaporizing source along a path wherein metal vapor flow lines connecting the center of the molten metal vaporizing source to points on the surface of the support form a constant angle of incidence with the longitudinal direction of the support. An adjusting mechanism is provided to change the angle of incidence by moving the transporting means along lines parallel to the metal vapor flow lines.
