    摘要： In an optical recording medium, even when a plurality of recording and reading layers are stacked, deterioration in the recording and reading signal quality thereof is suppressed. Furthermore, the transfer rate thereof can be increased. When recording or reading information by means of light irradiation on or from an optical recording medium having a plurality of recording and reading layers which are stacked in advance or formed eventually, an optical recording and reading device includes: a first optical system for irradiating a first beam to recording and reading layers to be a first target to perform recording or reading of information; and a second optical system for irradiating a second beam to recording and reading layers to be a second target to perform recording or reading of information.

    摘要： The multilayer optical recording medium with at least four or more recording and reading layers disposed one above the other has at least two or more recording and reading layer groups each including the recording and reading layers successively disposed one above the other. In adjacent recording and reading layer groups with an intermediate layer interposed therebetween, a recording and reading layer nearest a front side in the recording and reading layer group nearer a back side is higher than the higher value of the reflectances in a stacked state of two recording and reading layers nearest the back side in the recording and reading layer group nearer the front side.

    摘要： An object of the present invention is to increase the number of stacked layers in a multilayer optical recording medium while simplifying the design of the multilayer optical recording medium is provided a multilayer optical recording medium including at least four recording and reading layers from which information can be reproduced by light irradiation, the layers stacked through intermediate layers. The multilayer optical recording medium includes a plurality of recording and reading layers that are continuous in order of stacking and includes at least one recording and reading layer group in which reflectance in a stacked state decreases from a near side of a light incident surface to a far side. A single-layer reflectance of the nearest recording and reading layer is set to 0.2% or more and less than 2.0%, and a light transmittance improvement process is applied to the light incident surface.

    摘要： The multilayer optical recording medium with six or more recording and reading layers disposed one above the other has at least two or more recording and reading layer groups. The recording and reading layer groups each include a plurality of recording and reading layers successively disposed one above the other. The reflectance of each of the recording and reading layers in a stacked state decreases in the order from a front side near a light incident surface toward a back side far from the light incident surface. A recording and reading layer nearest the front side among the recording and reading layers in the recording and reading layer group nearer the back side has a reflectance in a stacked state higher than that of a recording and reading layer nearest the back side among the recording and reading layers in the recording and reading layer group nearer the front side.

    摘要： Simple design of a multilayer optical recording medium is achieved while suppressing interlayer crosstalk and confocal crosstalk in the multilayer optical recording medium. Simple recording and reading control by a recording and reading unit is also achieved. The multilayer optical recording medium includes at least three or more recording and reading layers deposited one above the other with intermediate layers interposed therebetween, and information can be read by light irradiation from the layers. The intermediate layers have film thicknesses of two types or less, and all the recording and reading layers except the recording and reading layer farthest from a light incident surface have substantially the same optical constant.

In the series of optical recording media, optical recording media are of a plurality of types, each optical recording medium including a plurality of planar recording and reading layers with no projections and depressions for tracking control, and a servo layer with projections and depressions for tracking control. The plurality of optical recording media have different numbers of stacked recording and reading layers, and the positions of the servo layers with respect to the corresponding light incident surfaces are standardized among the plurality of optical recording media.
