ABSTRACT:
A phase-change recording material on which high speed recording/erasing is possible, which has excellent recording characteristics, which has a high storage stability of recording signals and which is excellent in the repeated recording durability, and an information recording medium using the above material are provided. A phase-change recording material characterized by containing as the main component a composition represented by {(Sb1−xGex)1−yIny}1−z−wMzTewwherein x, y, z and w are numbers satisfying 0.001≦x≦0.3, 0≦y≦0.4, 0≦z≦0.2 and 0≦w≦0.1, and M is at least one element selected from lanthanoids, provided that z and w are not 0 at the same time.
