PARYLENE POLYMER COATING TECHNOLOGY FOR OPTICAL RECORDING MEDIUM, REALIZING ADVANCED HIGH-DENSITY OPTICAL RECORDING MEDIUM

摘要

PURPOSE: A parylene polymer coating technology for an optical recording medium is provided to coat an optical recording medium with a parylene polymer protecting film having excellent wear-resistant, chemical-resistant, water-resistant, and heat-resistant properties, thereby realizing high density of the optical recording medium. CONSTITUTION: A protecting film(11) having a thickness of about 10 micrometers is formed on a polycarbonate material(10). A recording layer(12) having a thickness of 100 to 200nm is formed on the protecting film(11). A reflective film(13) having a thickness of about 100nm is formed on the recording layer(12). A protecting film(14) having a thickness of 10 micrometers is formed on the reflective film(13). A parylene polymer protecting film(15) is formed on the protecting film(14) in perfect sealed type.
