摘要： An optical memory medium is described comprising prepits (11, 11') on which a light spot (5) is impinged to obtain information and, if required, guide grooves: each of those (11') among the prepits (11, 11') which are longer than the diameter of the light spot (5) consists of a series of pit portions (11a) and unpitted portions (12); each of the prepits (23) is sandwiched between two discontinuous portions (21a) of guide grooves (21) adjacent to each other; the guide grooves (21) have one or more narrow portions (21b), and each of the prepits (23) is sandwiched between two of the narrow portions (21b) of guide grooves (21) adjacent to each other; or the guide grooves (21) have one or more long portions (21h), one or more short portions (21j), and narrow portions (21i) formed between the long (21h) and short (21j) portions, and each of the prepits (23) is sandwiched between two of the short portions (21j) of guide grooves (21) adjacent to each other.

摘要： A novel optical recording medium and a method for manufacture thereof is disclosed, the optical recording medium, which is used as an optical disc or optical card et cetera for optically recording, reproducing, erasing and the like of information, comprising a center substrate having formed on at least either of both sides thereof recesses and/or protrusions, recording films formed on both sides thereof and transparent protective plates stuck to these recording films respectively, and featuring special arrangements to ensure against warping of the substrates constituting the optical recording medium and also against exfoliation of substrates or the like even when the optical recording medium is subjected to sudden changes in temperature as well as to allow placing emphasis on optical performance and protective effect in selecting the transparent protective plate regardless of the ease of forming recesses and/or protrusions such as grooves to thereby enable a marked improvement in its performance such as carrier-to-noise ratio and isotropy.

摘要： An optical disk of the present invention includes a transparent dielectric film formed on a light incident side of the disk on an opposite side of an optical recording film so as to sandwich the transparent substrate therebetween, for suppressing bimetallic effects caused by a difference in thermal expansion between an optical recording film formed on an optical recording surface and the transparent substrate, whereby changes in tilt against temperature changes can be suppressed. Further, by an optimal selection of a reflectance of the transparent dielectric film, unwanted reflection due to multi-interference can be reduced at the same time.
摘要翻译：本发明的光盘在光盘的与光学记录膜相反一侧的光入射侧上形成透明介质膜，以将透明衬底夹在中间，用于抑制由热膨胀差异引起的双金属效应在光学记录表面上形成的光学记录膜与透明基板之间，由此可以抑制对温度变化的倾斜的变化。此外，通过对透明介电膜的反射率的最佳选择，可以同时减少由于多重干涉引起的不希望的反射。
