Information storage medium

摘要

An information storage medium consists of a polycarbonate substrate (11) and a recording layer (12) formed on the substrate and containing an AgTe eutectic alloy, carbon, and hydrogen. Information is recorded on the medium by forming pits in the recording layer upon radiation of a laser beam, and is reproduced by radiating a reproducing laser beam onto the recording layer in which the pits are formed and detecting reflectances.
