Abstract

PURPOSE: To increase both the wear resistance and the antistatic properties of a recording disk, by giving a treatment onto the surface of a recording disk made of the vinyl chloride resin with the low-temperature plasma of the inorganic gas of ≤10 Torr and giving a contact to the recording disk with the halogen or the like.
CONSTITUTION: A treatment is given to the recording disk 10 made of the vinyl chloride resin with the low-temperature plasma of the inorganic gas of ≤10 Torr. For the plasma generating conditions, an electric power of 13.5MHz and 10 to several kilowatts is applied between the electrodes, and the time of treatment is generally from several seconds to several tens of minute although it differs according to the applied voltage. Then a contact is given to the surface of the recording disk with the gaseous or liquid halogen or the hydrogen halogenide. The contact pressure is set at ≥10 Torr, and the time of contact is usually set at several tens of second to several tens of minute although it differs according to the degree of pressure, the temperature of gas, the surface temperature of a formed product and other factors. In such way, the surface of a recording disk can be reformed to increase not only the surface strength but the wear resistance and the antistatic properties respectively.
