摘要： An optical-magnetic recording medium utilizing a recording layer of an amorphous rare-earth-transition metal alloy so as to rely on the Kerr effect. An enhancing layer of ZnS and a fluoride of an alkaline-earth metal (preferably CaF.sub.2) is deposited on a grooved substrate and the recording layer deposited thereover to both enhance the Kerr effect and prevent peeling.

摘要： The present invention relates to an optical recording disc comprising two disc bases each having a recording layer formed on one surface side of a substrate bonded to each other by the medium of an adhesive layer with both recording layers facing each other. The adhesive layer, containing an adhesive and a reaction initiator, is hardened through polymerization reaction by the reaction initiator and photopolymerization reaction by ultraviolet-ray irradiation. For this reason, the adhesive layers of both disc bases can be bonded together entirely and uniformly and besides, the adhesive layer can rapidly get hardened, which is advantageous for enhancing productivity of a double-face type optical recording disc.

摘要： There is provided a substrate for an optical recording disk capable of preventing non-uniformity of thickness of the transfer layer due to a camber of the substrate, and having a transfer layer excellent in uniformity of the thickness thereof. The substrate for the optical recording disk is manufactured in such a manner that a portion ranging from a center portion to an outer circumferencial portion of the substrate is forcively deformed in advance prior to the formation of the transfer layer so as to provide substantially a conical-convex shape, and thereafter, the transfer layer is formed onto a surface side of the conical-convex shape of the substrate.
摘要翻译：提供了一种用于光学记录盘的基板，其能够防止由于基板的弯曲而导致的转印层厚度的不均匀性，并且具有优异的厚度均匀性的转印层。用于光学记录盘的基板的制造方法是，在形成转印层之前，从基板的中心部分到外圆周部分的部分预先被强制变形，从而提供基本上圆锥形的光盘，然后将转印层形成在基板的圆锥形状的表面侧。
