摘要： At the least, a first recording layer 2 and a translucent film layer 3 are laminated in order on a transparent substrate 1 to form a first information recording/reproduction unit; and at the least, a reflective film layer 6 and a second recording layer 5 are laminated in order on a transparent substrate 7 to form a second information recording/reproduction unit. Then, the first and the second information recording/reproduction units are glued together by a transparent bonding layer 4, with the translucent film layer 3 facing the second recording layer 5, so that a two-layer information recording medium is obtained. Further, grooves G and lands L are formed for the first and the second recording layers 2 and 5. The depths of the grooves are substantially equal for the first and the second recording layers 2 and 5, the heights of the lands L are substantially equal for the first and the second recording layers 2 and 5, and the depth of the grooves G are greater than the height of the lands L.

摘要： An optical disk includes a substrate covered with an information recording layer. The information recording layer includes a recording material and a dispersion material dispersed in the recording material. The recording material absorbs recording light for recording information, and then generates heat. As the light refraction index of the recording material changes due to the heat generation, information is recorded on the recording material. The dispersion material has lower absorptance of the recording light and lower thermal conductivity than the recording material, and an external dimension smaller than a diffraction limit of reading light for reading information.

摘要： An optical disk includes a substrate covered with an information recording layer. The information recording layer includes a recording material and an exothermic material dispersed in the recording material. The exothermic material absorbs recording light for recording information, and then generates heat. An external dimension of the exothermic material is smaller than the diffraction limit of reading light for reading information. The recording material has absorptance of a wavelength of the recording light lower than that of the exothermic material. Information is recorded on the recording material as the light refraction index of the recording material changes due to heating.

摘要： An optical disc (100) from which a plurality of pieces of information recorded along a track (9) by irradiating light that moves above the track relatively are reproduced in parallel. The optical disc has a disc substrate (1), and a recording layer (2) formed thereon. On the recording layer, a track is defined concentrically and two pit rows for carrying the plurality of pieces of information independently from each other are arranged along the track on the opposite sides thereof. At a specific position where the two pit rows are in a predetermined mutual relation and the plurality of pieces of information read out by irradiating light cannot be distinguished, at least one of two pit rows is shifted by a predetermined distance in the radial direction of the disc substrate by having the track as reference. Consequently, recording capacity can be increased relatively easily.
