気記録媒体の製造装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an evaporation apparatus used for vacuum evaporation, etc., and particularly to a magnetic recording medium comprising a vapor flow control wall surface between a substrate and a ferromagnetic material evaporation source. This relates to manufacturing equipment.
近年、記録密度が一段と優れたものとして、強磁性材料
を薄膜として基体上に被着してなる、所謂金泥薄膜型磁
気記録媒体が注目を集めている。In recent years, so-called gold mud thin film magnetic recording media, which are formed by depositing a ferromagnetic material as a thin film on a substrate, have been attracting attention as a medium with even higher recording density.
この様な金泥薄膜型磁気記録媒体は、通常真空状態で、
蒸着・スパッタ等によって製造されるものである。Such a gold mud thin film type magnetic recording medium is usually in a vacuum state.
It is manufactured by vapor deposition, sputtering, etc.

より蒸発させられる。An example of a conventional vapor deposition apparatus will be described with reference to FIG. 2. A vacuum [1] is maintained in a vacuum atmosphere by a vacuum pump 14, and a ferromagnetic material 3 is heated with electrons by an electron gun power source 16 in an evaporation source 2b. It is vaporized by the electron beam emitted from the gun 15.

特開昭57−194252号公報参@) 。The basic device was that a gap 19 was provided between the evaporation source 12 and the vapor flow control wall surface 18 in order to secure a passage 17 for the electron beam. However, this gap 19
Since the vapor of the ferromagnetic material 3 from the evaporation source 2b was scattered and the evaporation efficiency was not good, we decided to use the evaporation source 2b as an improved device.
The vapor flow control wall surface 18 is connected to the vapor flow control wall surface 1 so that the electron beam can be incident from the upper part of the vapor flow control wall surface 18.
8 has been disclosed in which a part of it is expanded outward (for example, see Japanese Patent Application Laid-open No. 57-194252@).

点を持っていた。However, it is still difficult to improve the evaporation efficiency with electron beam evaporation equipment, and furthermore, when current heating is used to heat the vapor flow control wall surface, the electron beam of the electron gun is focused due to the influence of the current flowing through the wall surface. This had the disadvantage that the magnetic field used for this process was disturbed, making it impossible to obtain a sufficient evaporation rate.

In a, heating is performed by high-frequency induction heating using a high-frequency induction heating power source 5 using a heating coil 4. On the other hand, the polymer molded substrate 9 is sent out from the delivery roll 6, vapor of the ferromagnetic material 3 whose incident angle is regulated by the mask 10 is vapor-deposited on the vapor deposition drum 7, and then wound onto the take-up roll 8. Since the evaporation source 2a is heated by high-frequency induction heating, the vapor flow control wall surface 11 is disposed directly above the evaporation source 2a and completely surrounds the vapor flow path. The vapor flow control wall surface 11 is electrically heated by a power source 12 in order to prevent adhesion and accumulation of evaporated vapor, and is further surrounded by a heat insulating material 13, so that the temperature can be controlled.

Therefore, vapor components other than those that have reached (evaporated) the polymer molded substrate 9 on the evaporation drum 7 are also captured by the vapor flow control wall 11 and are not re-evaporated or was melted and recovered, making it possible to improve vapor deposition efficiency.

かった。A polyethylene telescrate film of 100 mm width and 13 μm thickness was used as the base of the polymer molding, a diameter of 3001 m (surface temperature of about 0°C) was used as the vapor deposition drum, and tungsten (W) (inner diameter of 50 mm, height of 90 mm) was used as the vapor flow control wall. The steam flow control wall used was placed directly above the Geishagen crucible without any gaps. The output of the high frequency power supply is 9KW, and the conveyance speed of the polymer molded substrate is 15m/min, approximately 1500 m/min.
As a result of evaporating Co with human film thickness, the evaporation efficiency was 19%.
I got it. In addition, since the vapor flow control wall is placed directly above the evaporation source, it receives a large amount of radiant heat from the evaporation scene. No adhesion deposition occurred on the control wall.

A vapor flow control wall (tungsten (W), inner diameter 50 am, height 50 mm) was installed with a gap of 4 Qma from the evaporation source to ensure a path for the electron beam. The output of the electron gun was 5KW, the conveyance speed of the polymer molded substrate was 5 m/min, and the vapor flow control wall was set at 5V, 8
Co was deposited while heating with a current of 00A. However, due to the current applied to the vapor flow control wall for heating, the electron beam could not be sufficiently focused, and a deposited film thickness of only about 800 nm could be obtained. Note that the vapor deposition efficiency at this time was 8%.
また、参考のために、蒸気流制御壁面を用いない場合の
蒸着効率は、4%であった。Also, for reference, the vapor deposition efficiency when no vapor flow control wall was used was 4%.

寄与した。The present invention provides a magnetic recording medium manufacturing apparatus comprising a vapor flow control wall surface between a substrate and a ferromagnetic material evaporation source under vacuum, wherein the vapor flow control wall surface is disposed directly above the evaporation source,
The evaporation efficiency from the evaporation source is significantly improved by using a magnetic recording medium manufacturing apparatus that completely surrounds the vapor flow and by using high-frequency induction heating means as the evaporation heating means. I was able to do it. Furthermore, since the evaporation rate can be increased sufficiently, it is possible to increase the thickness of the deposited film and to significantly increase the deposition rate, which greatly contributes to quality improvement and cost reduction in the production of magnetic recording media.
