Abstract

PURPOSE:To increase the utility of magnetic material, by using the material of the same composition as the evaporated magnetic material as the mask shielding the flow of magnetic material evaporation, in the manufacture of magnetic recording medium with the vacuum deposition method. CONSTITUTION:The cleaning can 1 is located in the vacuum vessel, and the tape shape substrate 2 made of flexible macro molecular material is moved along the external circumference of the cooling can 1. Further, the evaporation crucible 3 in the vacuum vessel is located downward the cooling can 1 and the ferromagnetic substance 4 is evaporated toward the cooling can 1. Further, the mask 6 is placed to the substrate 2 so that the evaporation flow 5 having a certain range of incident angle only can reach the substrate 2. As the material of the mask 6, the same composition as the ferromagnetic substance 4 charged in the evaporation crucible 3 is used. Thus, even if the ferromagnetic material 4 is adhered on the mask 6, the mask 6 is charged in the crucible 3 as it is and can be reused as the ferromagnetic substance 4.
