摘要： An optical disk medium in which high density recording/reproducing is possible, an information recording method and an information reproducing method using it are provided. A pit composed of a phase change material and a recording film different from it are provided on an optical disk. The phase change pit has a pattern of a single frequency. A mark having a size on the same level as the phase change pit can be formed by melting a single phase change pit while recording and controlling the optical absorbance and the temperature of the recording film at the region. A single phase change pit is molten while reproducing. Since the optical characteristics of the molten region are different from the optical characteristics of other regions, only data at the molten region can be reproduced by a super-resolution effect.

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： 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.

摘要： The optical recording medium has sandwiched between protective layers a mask layer whose refractive index is changed in one part within a light spot when irradiated with a laser beam of 2 to 4 mW. In a region where the refractive index is changed or in other remaining regions, the difference in the amount of reflected light between the crystalline state and the amorphous state is so small that a reproduced signal is difficult to identify. By reducing the size of a portion where the reproduced signal can be seen, it is possible to read high-density recorded information.

摘要： In an optical disk in which a recording layer is selected by applying voltages, a different address pit is formed in each recording layer. To this end, a plurality of recording layers are formed in a way that the plurality of recording layers follow a concavo-convex shape formed in a substrate, and thus the plurality of recording layers keep the concavo-convex shape even after the formation; mutually different address marks are add-on written, as a part of the address information, respectively to recording layer so that the address and track information can be confirmed in each layer.
