Abstract
A magnetic recording medium manufacturing apparatus is comprised of a cooling rotary cylinder can and a small roller, arranged adjacent to each other. A flexible endless belt is laid over the can and roller and carries a tape-shaped support. A ferromagnetic material, evaporated from an evaporation source disposed below the can and roller, is vacuum-deposited onto the tape-shaped support.
