OPTICAL RECORDING MEDIUM AND A METHOD OF PRODUCING THE SAME |
摘要 |
<p>A recording layer (4) recording optically readable data is formed on a rectangular substrate (1), and a protection layer (5) is formed by roll coating on the recording layer (4). The substrate (1) having the recording layer (4) and the protection layer (5) is divided into pieces of a predetermined shape. Here, the protection layer (5) formed on the recording layer (4) is composed of a material having a small Young's modulus and a thermal conductivity which is smaller than that of the substrate (1).</p> |
