Method for fabricating an information signal recorded medium of the electrostatic capacity type |
摘要 |
A method of fabricating an information signal recorded medium of the electrostatic capacity type is disclosed. The medium is made of a vinyl chloride resin composition comprising a conductive material such as carbon black. The resin composition is applied with water or steam when kneaded at high temperatures, by which deposition of undesirable inorganic impurities such as alkali metal or alkaline earth metal salts on the medium surface can be avoided as will otherwise be experienced. The water or steam is substantially removed by completion of the kneading.
