    摘要： A method for reproducing data according to the present invention is adapted for reproducing data recorded in an optical recording disc including a multi-layered body formed by forming a decomposition reaction layer containing noble metal oxide as a primary component and a light absorption layer so as to sandwich a dielectric layer therebetween by irradiating a laser beam onto the optical recording disc and forming a recording mark train including at least one of a recording mark having a length shorter than a resolution limit and a blank region having a length shorter than the resolution limit therein, and is constituted by changing the read power Pr of the laser beam in accordance with a readout linear velocity at which data are to be reproduced from the optical recording disc. According to the thus constituted method for reproducing data, even in the case where the length of a recording mark or the length of a blank region between neighboring recording marks is shorter than the resolution limit, it is possible to record and reproduce a recording mark train including these recording marks and the blank regions. Therefore, this method can be applied to an optical recording medium whose storage capacity is markedly increased.

    摘要： The invention discloses a flat-plate lens to be built in an optical recording medium for improving the image-forming characteristics of the recording medium. The flat-plate lens of the invention comprises a layered thin film having a periodical structure in the direction of thickness thereof corresponding to a wavelength slightly longer than the wavelength of the light used for recording and retrieving information into and from the recording medium. The thin film of a periodical structure is formed by alternate lamination of pluralities of layers two materials having different refractive indices such as a combination of MgF2 and ZnS. When the thin film having such a periodical structure is formed with good uniformity allover the surface, the image-forming performance on the recording layer can be uniform irrespective of the position on the flat-plate lens.

    摘要： A multi-layer structure whose volume changes when a temperature exceeds a predetermined threshold value, a microscopic structure drawing method that involves emitting a laser beam onto the multi-layer structure to create a temperature distribution within a beam spot and performing microscopic recording on a portion of the beam spot having a temperature higher than the threshold value, an optical disc master, and a mastering method using the same, where the multi-layer structure includes a substrate and a transformation layer formed on the substrate, wherein a volume of a portion of the transformation layer irradiated by a laser beam changes when the temperature of the portion exceeds a predetermined temperature. The microscopic structure drawing method includes emitting the laser beam onto a predetermined region of the transformation layer and heating the region of the transformation layer irradiated by the laser beam beyond a predetermined temperature so that the heated region can undergo a volume change.
