ABSTRACT:
In an optical disk, a single recording layer is formed on a transparent substrate. The recording layer has an insulative base layer in which metal clusters and organic clusters are uniformly contained. When radiation is incident on the recording layer such that the intensity of the radiation is changed in accordance with the type of recording information, the metal clusters absorb radiation energy. The organic clusters produce a gas component in accordance with a level of the radiation energy absorbed by the metal clusters, thereby causing the base layer to incur a local projection by a pressure of the gas component such that a protuberance is formed on the base layer.
