发明名称 INFORMATION RECORDING MEDIUM
摘要 In an information recording medium on and from which information is recorded and reproduced by applying light or electric energy, a recording layer which generates reversible phase change is formed so as to include a material containing Ge, Bi, Te and an element "M" which material is expressed with (GeTe) x [(M 2 Te 3 ) y (Bi 2 Te 3 ) 1-y ] 100-x (mol %) wherein "M" represents at least one element selected from A1, Ga and In, and "x" and "y" satisfy 80‰¤x<100 and 0<y‰¤0.9, whereby the medium is obtained which ensures a high erasability and an excellent archival characteristic at a high linear velocity and in a wide range of linear velocities.
