Abstract

PURPOSE:To ensure the effective recording even with the laser beam of a low light source intensity, by forming the transparent heat insulated layer made of the fluororesin having a smaller heat conductivity than the substrate onto the transparent resin substrate and then providing the optical recording film on the insulated layer. CONSTITUTION:Transparent heat insulated thin layer 6 using the fluororesin such as the polychlortrifluoethylene or the like having a smaller heat conductivity than transparent resin substrate 1 composed of the acrylic resin, vinyl chloride resin, polyester resin or the like onto substrate 1. And then optical recording thin film 2 composed of the amorphous oxide or the like the refractive index or the light absorbing coefficient of which varies by irradiation of the laser beam is provided on layer 6. The optical recording component thus obtained uses the fluororesin thin film excelling in both the heat insulating performance and the heat resistant performance, and accordingly the heat of the laser beam is not dispersed. And thus film 2 can be heated up effectively for carrying out the recording.
