摘要:
A rewritable optical information recording medium including a recording layer composed of an organic dye film is provided, in which recording and erasing information can be performed reversibly by laser light irradiation. A rewritable optical information recording medium including at least one organic dye film which is substantially made of only at least one kind of organic dye compounds as a recording film is provided. The recording and erasure of information are performed by a reversible physical change of the organic dye film substance caused by laser light irradiation. Specifically, data recording is performed by a physical change locally caused by the irradiation of recording laser light, data reproduction is performed by detecting change in intensity of returned light of reproducing laser light having less power than the recording laser light, and data erasure is performed by applying at least once continuous light or pulse light having laser power more than the reproducing laser light and less than the recording laser light. The physical change is a change in shape.
摘要:
An optical recording medium having two or more information recording layers in which information is recorded at a high recording density. The optical recording medium is comprised of information recording layers between a first surface at which light is incident and a second surface opposite the first surface. The first information recording layer nearest to the second surface is a phase-modulation information recording layer, and the second information recording layer is a reflectance-modulation information recording layer.

摘要:
An optical information recording medium including a recording layer that can record a large amount of information is manufactured using a simple system. A single recording layer is formed by bonding two optically transparent substrates on which the first photosensitive polymer and the second photosensitive polymer are spread such that the layers of the photosensitive polymers face each other. Furthermore, since the absorptivity of light in the recording layer increases as the focal point of light for information recording moves in a depth direction, information can be recorded without decreasing the recording transfer rate of the information.
摘要:
The invention is able to enhance a recording speed. In the invention, a recording mark (RM) composed of a cavity is formed by vaporizing a two-photon absorbing material by a two-photon absorption reaction as an embodiment of a photoreaction against a recording light beam (L1) as recording light to be condensed at the time of recording information. Also, in a recording layer (101), the information is reproduced on the basis of a return light beam (L3) formed by modulation of a readout light beam (L2) irradiated as prescribed readout light at the time of reproducing inform in conformity with the presence of absence of the recording mark (RM). Then, in the recording layer (101), in view of the fact that the a two-photon absorbing particle having a two-photon absorbing material coordinated with a metal fine particle (MN) is dispersed in a binder resin configuring the recording layer (101), the two-photon absorbing material having a two-photon absorbing characteristic is disposed as a vaporizable material in the vicinity of the metal fine particle (MN) dispersed in the binder resin.
