摘要： An information readout method for an optical information medium comprising an information recording layer having pits or recorded marks representative of information data involves the step of irradiating a laser beam to the information recording layer through an objective lens for providing readings of the pits or recorded marks. When the laser beam has a wavelength λ of 400 to 410 nm, the objective lens has a numerical aperture NA of 0.70 to 0.85, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 0.4 mW for the laser beam. When the laser beam has a wavelength λ of 630 to 670 nm, the objective lens has a numerical aperture NA of 0.60 to 0.65, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 1.0 mW for the laser beam. Pits or recorded marks of a size approximate to the resolution limit determined by diffraction can be read out at a high C/N.

摘要： The present invention relates to a method for processing a photoresist-coated board, a method for manufacturing a stamper for a recording medium and a method for manufacturing a recording medium which can form a fine raised and depressed pattern having a uniform width after development even in the case where a laser beam having a relatively long wavelength is used for forming pre-pits on a recording medium with high accuracy. A photoresist-coated board 108 is constituted by laminating a light absorption layer 108b and a photosensitive material layer 108c on a glass substrate 108a in this order and is exposed to a laser beam 102 by condensing the laser beam 102 onto the photosensitive material layer 108c, thereby forming a raised and depressed pattern corresponding to pre-pits on the the photosensitive material layer 108. When the length of a pre-pit to be formed is shorter than 4 T, for example, the duty ratio of the pulse signal train input to the light modulator 109 is varied within a range from about 50% to 65% so that a pulse signal train having a higher duty ratio is generated as the length of a pre-pit to be formed becomes longer and the power of a laser beam is modulated by the thus generated pulse signal train. On the other hand, when the length of a pre-pit to be formed is equal to or longer than 4 T, for example, a pulse signal train having a constant duty ratio is generated independently of the length of the pre-pit to be formed and the power of a laser beam is modulated by the thus generated pulse signal train.

摘要： A multilayer optical recording medium is provided with a totally reflective first information layer provided on a substrate and a second information layer being a translucent information layer provided via a spacer layer. The second information layer is composed of a TiO2 layer, a first dielectric layer, a reflective film, a second dielectric layer, a recording film, and a third dielectric layer, all of which are laminated together in this order. The first dielectric layer is made of ZrO2, Cr2O3, and Al2O3, and has a refractive index in the range of 1.84 to 2.20. If the recoding film is made of a material containing Sb as a main component, it is possible to strike a balance between high values of both the transmittance and the degree of modulation in recording information by laser light with a wavelength of 405 nm using an optical recording system having an optical system with a numerical aperture NA=0.85.

摘要： It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers whereby a sufficiently high erasing efficiency can be ensured when data recorded in any one of the information recording layers are directly overwritten. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto via a light incidence plane 13a. In the case where information is to be recorded in the optical recording medium 10, information is recorded in the L0 layer 20 using an off-pulse recording format and information is recorded in the L1 layer 30 using an on-pulse recording format. As a result, even in the case of directly overwriting data recorded in either of the L0 layer 20 or the L1 layer 30, a sufficiently high erasing efficiency can be ensured.
