INFORMATION RECORDING MEDIUM

摘要

An information recording medium comprising a substrate and superimposed thereon a recording layer composed of Sb, Te and Ge has been found to be advantageously employed, because of its nigh thermal stability as well as high sensitivity and high S/N ratio, in a system of recording information by exposing an energy beam to a recording medium to cause the exposed areas to be different in optical extinction coefficient from the non-exposed areas.
