<P>PROBLEM TO BE SOLVED: To provide an optical recording medium which is highly evaluated in terms of recording sensitivity, image contrast before and after recording, regenerated signal (C/N ratio) and environmental resistance. <P>SOLUTION: The optical recording medium has two recording layers, i.e., a first recording layer (2) and a second recording layer (3). The first recording layer (2) is an alloy layer comprising In or Sb, and one element selected from among Ti, Pd, Zr and V, and the second recording layer is composed of Si or Ge. <P>COPYRIGHT: (C)2003,JPO |
