    • An optical recording medium comprises a light transmissive substrate, a record film formed on a surface of the base plate, the record film containing phthalocyanine as a coloring matter, a light-reflection film formed on a surface of the record film, and a protection film formed on a surface of the light-reflection film, the protection film having a thickness capable of preventing the light-reflection film from braking by a deformation thereof in directions to the light-reflection film and the protection film due to a formation of a pit in the record film. The data is recorded in the recording medium by irradiating a light from a side of the light transmissive substrate, melting and sublimating phthalocyanine in the record film to effect the deformation to the directions of the substrate, the light-reflection film and the protection film, and forming a cavity in the substrate and a capsule portion in the record film to cover the cavity, the capsule portion having a composition different from that of the record film.
    • 光记录介质包括透光基板,形成在基板的表面上的记录膜,记录膜含有酞菁作为着色物,形成在记录膜表面上的光反射膜和保护膜 形成在光反射膜的表面上,保护膜具有能够防止由于形成凹坑而导致的光反射膜和保护膜的方向上的变形而产生的光反射膜的厚度 在录影片中。 通过从透光性基板的一侧照射光,在记录膜中熔融升华酞菁来实现向基板,光反射膜和保护膜的方向的变形,将数据记录在记录介质中, 在基片上形成空腔,在记录膜上形成胶囊部,以覆盖空腔,胶囊部分的组成与记录膜不同。
