Abstract
PURPOSE:To improve the performance of antistatic properties and of wear resistance of record discs, by moving a polyvinyl chloride resin record disc while rotating it between two rows of electrodes in an internal electrode discharge type low temperature plasma generator, for gaseous inorganic plasma processing. CONSTITUTION:In an internal electrode discharge type low temperature plasma generator, a plurality of rod shaped electrodes 1 are arranged in parallel in two rows, for example, and one row is taken as a high frequency power supply input side + and another row is taken as ground side -. A polyvinyl chloride resin record disc 3 is fitted to a shaft 7 at the tip of an arm 6 of the driving device between the rows and it is moved while being rotated until the arm is almost horizontal. Movement is repeated for several seconds-several minutes and transposition is made five times while it. In the device, the pressure of 0.001-1Torr. is given and cooling water flows from an inlet 9 to an exit 9' at the electrode 1 in gaseous atmosphere such as He and Ar or the like, for the cooling under 60 deg.C or lower to achieve plasma processing in preventing thermal deformation of record discs. Thus, the entire surface of disc can uniformly be made, and performance of antistatic properties and wear resistance can be made without adverse effect on the sound quality.
