摘要： An optical recording medium (10) includes a substrate (12), a first dielectric layer (14), a recording layer (16), a second dielectric layer (18), a super-resolution layer (20), and a third dielectric layer (22), which are provided in that order. The super-resolution layer (20) 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 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.

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： 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.
