AN INFORMATION RECORDING MEDIUM |
摘要 |
<p>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 high 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.</p> |
