摘要： PURPOSE:To raise magnetic characteristics by ionizing one part in a vertical vapor-deposition process of a magnetic metal or an alloy vapor. CONSTITUTION:The inside of a vacuum enclosed vessel 1 is evacuated, and an evaporating material A of a prescribed composition is heated and evaporated by an electronic beam heating device 8. On the other hand, oxygen is led in from an oxygen leading-in pipe 11, and for instance, a positive DC voltage is applied to an electrode 12 connected to a DC power source 13. An electron from an electronic beam and a secondary electron from an evaporating liquid surface are attracted to a positive electric field, and a metallic vapor and an oxygen atom are partially ionized. In this state, the vapor of a magnetic metal is vapor- deposited roughly vertically to the lower face of a tape base material B fed out of a roll 4 passing through an opening 10 and running at a constant speed along the lower end face of a can 3 being right above said opening. In this way, a vertical magnetic tape having a vertically magnetized film (a) whose magnetic characteristic has been raised is obtained around a winding roll 5.
