INFORMATION RECORDING MEDIUM |
摘要 |
<p>An information recording medium comprising a substrate (1), a recording layer (2) formed on the substrate in order to record information, a color filter (4) formed on the substrate, and a thermal reflectance variation layer (3) formed on the substrate in order to vary light reflectance by heat incident to irradiation of light and to reflect visible light entering from one side of the substrate through a color filter. High precision color writing or color label writing can be carried out on an information recording medium such as DVD and BD where a label can be written on the surface by irradiating light.</p> |
