摘要： Stable tracking control is achieved for an optical recording medium having a plurality of information recording planes. To achieve this, an optical information device comprises a light source for emitting a light beam, a focusing unit for converging the light beam emitted from the light source onto a predetermined information recording plane of an optical recording medium having a plurality of information recording planes, a beam splitting unit for splitting the light beam reflected by the optical recording medium, and a light detection unit having a light receiver that receives the light beam split by the beam splitting unit, for outputting a signal corresponding to the light intensity of the light beams received by the light receiver. A guide groove is formed on at least one of the information recording planes, and the light receiver is entirely disposed within in a map formed on the light detection unit by the light beam reflected by an information recording plane other than the predetermined information recording plane.

摘要： An optical recording medium is provided having a plurality of laminated recording layers, wherein the recording layers are formed such that a spacing between each pair of recording layers of all recording layer combinations selected from the plurality of recording layers is different from that of each other pair. Accordingly, a return of lights reflected by other layers to an optical head along the same optical path as reflected light from a readout layer during the reproduction can be avoided. Therefore, use of the optical recording medium, from which a good reproduction signal can be obtained, can suppress a deterioration of a servo signal and a reproduction signal of a reproducing device due to a variation of interference fringes on a light receiving element.

摘要： An optical recording medium is provided with a plurality of recording layers, wherein the recording layers are formed such that all the spacings between two recording layers in all the combinations selected from the plurality of recording layers do not coincide with each other. Accordingly, the return of lights reflected by other layers to an optical head along the same optical path as reflected light from a readout layer during the reproduction can be avoided. Therefore, an optical recording medium, from which a good reproduction signal can be obtained, can be provided by suppressing the deterioration of a servo signal and a reproduction signal of a reproducing device due to a variation of interference fringes on a light receiving element.

摘要： The recording/reproducing quality of a multilayer optical information recording medium deteriorate not only due to interference from other layers caused by light converging on other information layers but also due to stray light converging on the surface of a protective layer and stray light that does not converge on other information layers but rather returns to an optical head through the same optical path as the reproducing signal. The thickness composition of intermediate layers (106, 107, and 108) and the protective layer (109) in a four-layer optical information recording medium are set so as to eliminate the influence of interference caused by stray light from other layers reflected up to three times.
