Abstract
The invention is to a method of manufacturing a recording medium, such as an optical information recording medium and a magnetic recording medium. By providing the surface of an optical information recording medium with a chemical adsorption film containing an alkyl fluoride through a siloxane coupling, a recording medium excelling in humidity resistance and corrosion resistance is obtained. By providing the surface of a magnetic recording medium with a chemical adsorption film containing an alkyl fluoride through siloxane coupling, a recording medium excelling in lubricity, durability, running performance and wear resistance may be obtained. Employing the vapor phase process, a plastic substrate may be used, and the formation of pin holes may be prevented.
Claims11
A method of manufacturing a recording medium having a recording layer on a surface of a plastic substrate, comprising first depositing the recording layer on the surface of the plastic substrate, then contacting a halogenated silane chemical adsorbent with the recording layer under vapor phase to induce a dehydrochlorination reaction, and reacting the chemical adsorbent with moisture to form a chemical adsorption film.
