Magnetic recording medium manufacturing device

Abstract

PURPOSE: To manufacture a magnetic recording medium with good surface property by providing a cooling roller to the exit of a high polymer film wound on a can. CONSTITUTION: When the high polymer film 13 wound on the can 14 passes through an upper part of a vapor-deposition source 15 installed oppositely to the can 14 at a prescribed speed, a magnetic metallic particle emitted from the vapor deposition source 15 is adhered on the high polymer film 13 so as to form continuously a metallic thin film on the high polymer film 13 supplied continuously from a winding roll 11. The high polymer film 13 adhered with the metallic thin film reaches a high temperature by the radiation heat from the vapor deposition source 15 in this case, the film is cooled while being in contact with the cooling roller 17 and wound on the winding roll 16 and then, no heat is stored in the winding roll 16 and a job for a long time is conducted while the winding roll is kept always to a low temperature.
