摘要:
An optical information recording medium (10) of the present invention includes a first substrate (11), a second substrate (12) placed in parallel with the first substrate (11), and an information layer (20) placed between the first substrate (11) and the second substrate (12), wherein the information layer (20) includes a recording layer (22) and a dielectric layer (lower dielectric layer (21)/upper dielectric layer (23)) placed so that a distance from the dielectric layer to the recording layer (22) is 20 nm or less. The recording layer (22) is changed between at least two different states that can be identified optically by irradiation of a laser beam (14) incident from the first substrate (11) side, and the dielectric layer contains ZnS and Si as main components.
