Abstract: PURPOSE:To allow the production of a magnetic film while controlling the temp. of a substrate film without having a temp. gradient by forming a substrate holder of a material having >=0.4[cal.cm<-1>.sec<-1>.deg<-1>] thermal conduction constant. CONSTITUTION:The substrate holder 6 is formed of the material having a good thermal conductivity and excellent workability and corrosion resistance, for example, silumin in order to eliminate the temp. gradient of the surface. This silumin is the material having >=0.4[cal.cm<-1>.sec<-1>.deg<-1>] thermal conduction constant. The substrate holder 6 is provided properly with passages 9 for passing hot water and the hot water for temp. control is passed in these passages 9.

The formation of the magnetic film while the temp. control is executed without generating the temp. gradient on the substrate film 2 is thus enabled. The magnetic film is produced while the temp. control is executed without generating the temp. gradient in this way and the perpendicular magnetic recording medium having the uniform reproducing output is produced.
