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 simple-structured recording medium without a mask layer and information recording and reproducing methods, which resolve thermal stability related problems arising during reproduction, the recording medium including a high melting point recording layer between first and second dielectric layers. The method of recording information on the recording medium involves irradiating a laser beam onto the recording medium to induce reaction and diffusion in the high melting point recording layer and the first and second dielectric layers. The method of reproducing information recorded on such a super-resolution near-field recording medium by the above method involves generating plasmon using crystalline particles of the high melting point recording layer and the first and second dielectric layers as a scatter source to reproduce information regardless of a diffraction limit of a laser used.

摘要： A method for determining a read power of a laser beam includes a step of setting a power of a laser beam to a recommended recording power Pw′ 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 in an optical recording disc, thereby recording test data therein. The method also includes a step of setting the power of the laser beam to a recommended read power Pr′ and reproducing the test data recorded in the optical recording disc, a step of judging whether or not signal characteristics of a reproduced signal obtained by reproducing the test data satisfies reference conditions, and determining an optimum read power of the laser beam based on the result of the judgment.

摘要： An optical disk primarily includes a recording layer and a viscosity-variable material layer. When a laser beam is irradiated to reproduce a record written on the recording layer, part of the crystalline thin layer of the viscosity-variable material layer is softened to vary the optical constant of the softened region. Consequently, a plane having discontinuous optical constants is produced at the boundary between the softened region and the other region, so that a ring-shaped specific region is produced in a light spot. The ring-shaped specific region allows record patterns smaller than or equal to the resolution limit to be reproduced with the same signal intensity as that of the other record patterns larger than the resolution limit.

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： In an optical information medium comprising an information recording layer having a mark train of marks and spaces, the mark train is read out by scanning it with a laser beam and detecting a light intensity change pattern of reflected laser beam. Provided that the reflected laser beam includes polarized light components which define an angle θ with the mark train, a polarized light component giving θ=0 is x0 component, and a polarized light component giving θ=90° is y0 component, the mark train is read out utilizing at least a light intensity change of x0 component. When pits or recorded marks having a size approximate to or below the resolution limit are read out, the present invention allows high read outputs to be obtained and prevents omission of readout signals.

摘要： An optical recording medium in accordance with the present invention is provided with a substrate, a mask layer, provided on the substrate, whose index of refraction changes due to light or heat of the substrate, and a recording layer that is provided away from the mask layer by a distance that is not more than a distance which allows the near-field light to reach. The mask layer generates a minute opaque region in a light spot and the recording layer is a magneto-optical layer. An optical recording and reproduction apparatus in accordance with the present invention uses the optical recording medium. This allows to provide an optical recording medium and an optical recording and reproduction apparatus that can suppress the erasure of recorded marks and carry out the reproduction again and again.
