ABSTRACT:
An optical recording medium which has a recording medium and a light reflective film on a substrate. A top coat film made of organic material for adjusting reflectivity is formed on a surface of the substrate opposite to the other surface on which the at least one of the recording film and the light reflective film is formed. A reflectivity is remarkably enhanced without any adverse affect to a tracking error and an error rate. Also, it is easy to form the top coat. The top coat has an excellent weatherproof property.
