PROBLEM TO BE SOLVED: To make it possible to surely produce magnetic recording media having prescribed magnetic characteristics over a long time. SOLUTION: The apparatus for production of the magnetic recording media which forms magnetic films by adhering the vapor flow of a magnetic material 11 regulated in the max. incident angleθmax and min. incident angleθmin by masks 9, 10 to a nonnagnetic substrate 6 is provided with a mechanism for changing the positions of plates 16, 17 disposed near the masks 9, 10 and the magnetic material 11 according to the change in the max. incident angleθmax and min. incident angleθmin .
