Information recording medium, method for producing the same, and recording/reproducing method using the same |
摘要 |
An information recording medium 10 of the present invention includes a first substrate 11, a second substrate 12 disposed so as to be opposed to the first substrate 11, a first information layer 13 disposed between the first substrate 11 and the second substrate 12, a second information layer 14 disposed between the first information layer 13 and the second substrate 12, and an intermediate layer 15 disposed between the first information layer 13 and the second information layer 14. The first information layer 13 includes a first recording layer 18 that is transformed in phase reversibly between a crystal phase and an amorphous phase with a laser beam 35, and the second information layer 14 includes a second recording layer 27 that is transformed in phase reversibly between a crystal phase and an amorphous phase. The first recording layer 18 contains, Ge, Sn, Sb, and Te, and has a thickness of 9 nm or less. <IMAGE> |
