Abstract: 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.

Abstract: An optical recording medium having two or more information recording layers in which information is recorded at high recording density. The incidence of light on the information recording layer disposed far from the top layer through which light enters and the returning light from the information recording layer can be detected at high efficiency. The recording/reproducing characteristics are favorable. An optical recording/reproducing method for at least reproducing/recording information from/on this optical recording medium is also disclosed. The optical recording medium (10) comprises information recording layers (21, 22) between a first major surface on which light can be incident and a second major surface opposed to the first major surface. The first information recording layer (21) nearest to the second major surface is a phase-modulation information recording layer, and the second information recording layer (22) is a reflectance-modulation information recording layer. Information is reproduced or recorded from or in the first information recording medium (21) of the optical recording medium (10) by a phase modulation method, and information is reproduced or recorded from or in the second information recording layer (22) by a reflectance modulation method.

Abstract: PROBLEM TO BE SOLVED: To enable a plurality of pulses to emit at a pulse interval shorter than a pulse period which can be generated by a laser beam source. SOLUTION: In an optical disk device 1, a pulse train creating section 11 causes the laser beam source 21 to emit the light beam L1 containing pulses P0 and a pulse conversion section 23 divides the light beam L1 into the pulse train PL composed of four pulses with the interval of about 1 [ns]. An optical pickup 7 converges the light beam L containing the pulse trains PL on a recording layer 101 by an objective lens 8. Thus, the optical pickup 7 can generate a reaction caused by an excited state absorption by second and succeeding pulses P2 to P4 while keeping the excited state of a recording material M which is generated by two-photon absorption of a first pulse P1 in the neighborhood of a focus F of the light beam L, and therefore a recording mark RM can be formed on a recording layer 101 in an extremely short period of time. As a result, an information recording speed of the optical disk device 1 can be improved. COPYRIGHT: (C)2011,JPO&INPIT
