摘要：
An optical disk and method of preparing it in which a macromolecular substrate has information bits mechanically formed on its surface and a reflective metallic reflective film is deposited thereover. The grain size of the metallic reflective film is kept to less than 50 nanometers by depositing at a rate of no more than 1.5 nanometers per second.
