ABSTRACT:
An information storage medium includes a substrate, and a recording layer formed on the substrate, which contains carbon, hydrogen, and Te. The recording layer has an amorphous state wherein no peak representing the presence of a crystal is confirmed by X-ray diffractometry, and an activation energy is 1.5 eV or more, which is required to transform the state of the recording layer from the amorphous state into a crystalline state wherein peaks each representing the presence of a crystal are confirmed by X-ray diffractometry.
