Abstract: An optical information recording medium 10 comprises a plurality of recording layers 14, and intermediate layers 15 each provided between the recording layers 14. Each of the recording layers 14 includes polymer binder and dye dispersed in the polymer binder, and the dye is subject to multi-photon absorption of a recording beam RB having a predetermined wavelength and to linear absorption not smaller than 1.5% per recording layer at the predetermined wavelength of the recording beam. When the dye is irradiated with the recording beam and generates heat by linear absorption and multi-photon absorption of the recoding beam RB, the polymer binder undergoes a change of shape by the generated heat, whereby an interface between the recording layer 14 and the intermediate layer undergoes a change of shape to record information.

Abstract: An optical information recording medium 10 comprises a plurality of recording layers 14 and intermediate layers 15 each provided between the recording layers 14. Each of the recording layers 14 includes a polymer binder and dye dispersed in the polymer binder, and a thickness of each recording layer is equal to or greater than 50 nm. A first interface (near-side interface 18) is formed between a recording layer 14 and an intermediate layer 15 that is adjacent to the recording layer 14 on one side of the recording layer 14 in a thickness direction of the recording layer 14, and a second interface (far-side interface 19) is formed between the recording layer 14 and an intermediate layer 15 that is adjacent to the recording layer 14 on the other side of the recording layer 14 in the thickness direction of the recording layer 14. When the dye is irradiated with a recording beam and generates heat by absorption of the recording beam, the polymer binder undergoes a change in shape by the generated heat, so that at least one of the first interface and the second interface undergoes a change in shape and sticks out toward the intermediate layer 15 to form a protrusion, whereby information is recorded in the optical information recording medium 10.
