摘要： An optical disk (10) comprises a substrate (11) for recording information and a light reflective metal thin film (12) formed on the substrate (11). A light beam is made incident to the substrate (11) and reflected by the metal thin film (12), and from the reflected light beam, the information can be read. At least 60% of the area of the metal thin film (12) is composed of crystals each of 500 Å or above in diameter.
