摘要： A recording layer including a recording magnetic domain for recording thereon information is formed. A reproducing layer for reproducing information by projecting thereto a light beam is formed on the recording layer. A non-magnetic intermediate layer for intercepting a magnetic exchange coupling force exerted between the recording layer and the reproducing layer is formed between the recording layer and the reproducing layer. The reproducing layer is arranged such that the width of the stable magnetic domain on the reproducing layer at room temperature is larger than the width of the recording magnetic domain in the recording layer. At a reproducing temperature by the light beam, the width of the stable magnetic domain becomes smaller than the width of the recording magnetic domain, and the information is copied by the leakage magnetic flux of the recording magnetic domain. Depending on whether or not the information transferred to the reproducing layer is reproduced, the effects from other magnetic domain adjacent to the magnetic domain to be reproduced from the reproducing layer can be prevented, thereby enabling a high density recording of information on the recording layer.

摘要： An optical recording medium, which is used as an optical disc, optical card or the like for optically recording, reproducing, erasing and the like, includes a center substrate having formed on at least one side thereof recesses and/or protrusions. Recording films are formed on both sides thereof and transparent protective plates bonded to these recording films respectively. This arrangement substantially eliminates warping of the substrates constituting the optical recording medium and exfoliation of substrates or the like even when the optical recording medium is subjected to sudden changes in temperature. This optical recording medium demonstrates enhanced optical performance and protective effect. The selecting of the transparent protective plate is simplified because the forming recesses and/or protrusions is not a factor. By producing an optical recording medium utilizing the above features, the carrier-to-noise ratio and isotropy of the medium is improved.

摘要： An optical disk includes a plurality of disk sheets which are laminated, and each of which has a recording face on one of the surfaces and a flat back surface, wherein the plurality of disk sheets are laminated by adhesive layers in such a manner that between adjacent two disk sheets, a back surface of one of the disk sheets, on the opposite side of the surface where the recording face is formed, faces the disk surface of the other disk sheet. The foregoing structure realizes an optical disk of desirable recording/reproducing characteristics, which is flat and has a fixed interval between recording faces, and which permits the problems of coma aberration, spherical aberration, etc., to be suppressed.

摘要： A method for forming micropatterns includes forming a thin film consisting of a single layer or of plural layers on a substrate, irradiating an energy beam to the thin film to elevate the temperature of a region to a predetermined temperature or higher to thereby modify the region of the thin film, and patterning the thin film at least in such a manner to leave over the modified region.
