    摘要： An information recording medium and an optical recording system allow target information (such as an ad) to be displayed without requiring changes in hardware or physical specifications. The recording medium comprises a recording-limited area in which recording is made possible by canceling the limit after an instruction is issued for displaying the target information.

    摘要： In an information memory apparatus having minute areas for storing information arranged in x, y and z directions three-dimensionally, parallel rays are irradiated to a memory area MA in a direction perpendicular to a z-axis to take projection images of the memory area MA while rotating the memory area MA around the z-axis little by little. The light rays irradiated at this time have a size which covers at least a direction of an x-y plane of the memory area. A computation unit PU finds data and addresses of minute areas distributed three-dimensionally by performing computation based upon the principle of computer tomography on the projection images. As for data writing, a change is given to optical transmissivity or light emission characteristics by irradiating laser light focused by a lens OL placed outside the memory area to a desired minute area and causing heat denaturation within the pertinent minute area.

    摘要： Regarding a signal recorded with a first frequency in a recording area on a specific first recording layer and a signal recorded with a second frequency different from the first frequency in a recording area on a second recording layer which might cause interlayer crosstalk in relation to the first recording layer, a reproducing signal measurement method for a multilayer optical recording medium having at least three recording layers includes reproducing the signal recorded in the recording area on the first recording layer, separating signals recorded respectively with the first and second frequencies, discriminating signal amplitude of the first frequency and a maximum value in signal amplitude of the second frequency, and calculating a signal amplitude ratio between them to measure interlayer crosstalk contained in the signal reproduced from the recording area on the first recording layer. Thus, the interlayer crosstalk quantity caused by unnecessary light can be measured quantitatively.

    摘要： Disclosed are an information reproduction method and an information recording medium that allow reproducing information below a diffraction limit. A recording layer formed with recording marks consisting of a nucleation inducer and a reading layer are provided. When a reading beam is irradiated, a predetermined area of the reading layer is crystallized based on the recording mark of the recording layer such that the area is magnified to a size larger than the recording mark, and information is thus reproduced. Information of the recording marks below the diffraction limit can be reproduced without using a special information reproduction apparatus.
