Patent ID: 7498069

Claim:
An optical recording medium, on which data is recorded by irradiating with a laser beam, comprising: a substrate; and a recording film which is formed on said substrate and whose status is changed by irradiating with said laser beam, wherein said recording film includes (αTe) x βTe 3 as a major component (x is a positive real number), said α is selected from the group consisting of Ge 1-a Sn a and Ge 1-a Pb a (a is a real number not less than 0 and not more than 1), and said β is selected from the group consisting of Sb 2-y In y , Sb 2-y-z In y Bi z and Bi 2-y In y (y and z are real numbers more than 0 and less than 2; y+z is more than 0 and less than 2).
