    摘要： 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.

    摘要： Disclosed herewith is a method for enabling fast and high density recording of information. A voltage is applied to a recording layer formed between a pair of electrodes. The distance between the pair of electrodes is set wider at one of land and groove areas of a subject optical disk and narrower at the other, or the disk has multi-recording layer structure and light absorption occurs only in the layer on which coloring voltage is applied. The optical disk is provided with a layer of which light absorption spectrum changes according to the application of voltage, thereby absorbing the light. The layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only in a selected area of the optical disk at the time of recording, the disk can also avoid cross-talks between layers during reading and can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording. The disk can thus be formed with easily selectable multiple layers.

    摘要： This invention is a write-once near-field optical medium using a zinc oxide nano-structured thin film as the localized near-field optical interaction layer. This write-once near-field optical medium is a multi-layered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which is made of transparent dielectric material; (c) a zinc oxide nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a second protective and spacer layer formed on the localized near-field optical interaction layer, which is also made of transparent dielectric material; (e) a write-once recording layer; (f) a third protective and spacer layer formed on the write-once recording layer, which is also made of transparent dielectric material. Ultra-high density near-field optical recording can be achieved by the localized near-field optical interactions of the zinc-oxide (ZnO) nano-structured thin film that is in the near-field region of the write-once recording layer.
