摘要： A proximity exposure method and apparatus therefor. Replications of mask patterns are carried out, wherein as a mask closely approaches a substrate, the displacement of the mask is detected, and the atmospheric pressure between the mask and the substrate, or around the side of the mask opposite the substrate is controlled so as to cancel the displacement of the mask. The apparatus includes positioning apparatus, a light source for exposing the mask pattern, displacement measuring means, and atmospheric pressure controlling means.

摘要： An organic compound having an affinity for a resin of a molded resin article and sublimation properties is allowed to penetrate/disperse into the surface of the molded resin article, thereby modifying and/or coloring a resin surface layer. The molded resin article and the organic compound having the affinity for the resin and the sublimation properties are put into a tightly closable container, and the pressure and the temperature in the container are adjusted to place them in a saturated sublimation pressure state of the organic compound, whereby a vapor of the organic compound is uniformly deposited on the surface of the molded resin article and it further penetrates/disperses into the resin surface layer, and in consequence, the resin surface layer can be modified and/or colored. In addition, the modification of the resin surface layer permits imparting a function thereto.

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 device and a recording medium are provided with a recording layer for recording information by radiation of light, and a mask layer which is formed closely to the recording layer, reduces its transmittance of light due to light or heat, and transmits light to the recording layer by using a near-field effect. An optical reproducing and recording method includes the steps of: emitting a laser beam onto the mask layer, generating a near field around an area of the mask layer that has transmittance being reduced by the laser beam, and reproducing or recording optical information in the recording layer by interaction between the near field and the recording layer. With this method, it is possible to provide the optical device, recording medium, and optical reproducing and recording method that can realize a high S/N ratio upon reproducing and recording and that can readily form a recording mark.
