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： 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： Disclosed is a photolithographic pattern-forming material capable of giving a fine patterned resist layer rapidly and being used repeatedly. The pattern-forming material is a multilayered body comprising a substrate and a photoresist layer thereon which is overlaid with a three-layered composite film for near-field light generation consisting of an intermediate layer of a non-linear optical material such as antimony sandwiched between two dielectric layers. When irradiated with active rays focused on the optically nonlinear layer, a fine optical window or light scattering point is formed therein where a near-field light is generated to pattern-wise expose the photoresist layer.

摘要： Provided is an optical probe array head device in which a single optical detector or a plurality of optical detectors are disposed to each of the optical probes constituting an optical probe array having a plurality of apertures. The optical detectors are arranged to surround the aperture so as to be able to efficiently detect scattering of a feeble near-field light enabling similtaneous detection of a multipilicity of optical signals. In this device, an optical lens system necessary for optical detection can be omitted by integrating the optical probe array and the optical detectors. In addition, the output signals from the optical detectors can be utilized for conducting position control of the optical probe array head.
