摘要： A super-resolution information recording medium, a recording/reproducing apparatus, and a recording/reproducing method uses an information recording medium provides a super-resolution effect by fluid bubbles. The fluid bubbles are formed in at least a portion of the medium by a light beam radiated to reproduce a signal from the information recording medium. Accordingly, the super-resolution information recording medium has improved optical characteristics, so that better recording/reproduction is possible.

摘要： An optical recording medium includes a substrate, a first dielectric layer, a recording layer, a second dielectric layer, a super-resolution layer, and a third dielectric layer, which are provided in that order. The super-resolution layer is formed of a material configured such that voids are generated when the material is irradiated with DC light at a predetermined irradiation power for 1 to 300 seconds. Therefore, super-resolution reproduction can be made such that the irradiation power of a readout laser beam does not depend on the size of a recording mark.

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.
