Abstract: An optical information recording medium comprises recording layers which include a polymer binder and a dye dispersed in the polymer binder or include a polymer to which a dye is bonded, and each recording layer has a refractive index unchangeable under irradiation with a recording beam, with first and second interfaces being defined between the recording layer and two intermediate layers adjacent thereto. Irradiation of a region of the recording layer adjacent to the first interface or a region of the recording layer adjacent to the second interface with the recording beam causes the dye to absorb the recording beam and generate heat which in turn deforms the polymer in the recording layer, forming a protrusive shape protruding into an intermediate layer at the first or second interface whereby information is recordable in separate information layers at both of the first and the second interfaces.

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.
