    • This invention relates to how to obtain an optical recording disc with a good quality, capable of achieving a beautiful outline shape of the inner peripheral part side rim part of the cured ultraviolet ray curing type resin substantially concentrically even in the case there is irregularity of the wettability of both round substrates with respect to the ultraviolet ray curing type resin, and capable of providing an even film thickness of the resin with the film thickness controlled to a predetermined value or less even in the case there are irregularity of the wettability of both round substrates, difficulty in controlling the centrifugal force applied on the resin, irregularity of the plate thickness of both round substrates, or the like. Either one of both substrates is rotated at a low speed with the other one fixed while pressuring between both substrates of an optical recording disc comprising both substrates temporarily bonded via a ring-like ultraviolet ray curing type resin disposed substantially concentrically with the substrates for forming a layer with a predetermined even thickness by the spread, the optical recording disc temporarily bonded having the layer-like resin is rotated at a high speed, and an ultraviolet ray is irradiated to the optical recording disc temporarily bonded and rotated at the high speed for curing the layer-like resin.
    • 本发明涉及如何获得具有良好质量的光学记录盘,能够实现同时固化的紫外线固化型树脂的内周部边缘部分的美观轮廓形状,即使在不规则的情况下 两种圆形基材相对于紫外线固化型树脂的润湿性,即使在两面的润湿性不均匀的情况下,也能够使膜厚控制在规定值以下的树脂的均匀膜厚 基板,难以控制施加在树脂上的离心力,两个圆形基板的板厚度不规则等。两个基板之一都以低速旋转,另一个基板在两个基板之间压力固定的同时固定 光学记录盘,其包括通过环状紫外线固化型树脂disp临时粘合的两个基板 与用于通过扩展形成具有预定均匀厚度的层的基板基本上同心地旋转,具有层状树脂的临时粘合的光学记录盘以高速旋转,并且将紫外线暂时照射到光学记录盘 粘合并高速旋转以固化层状树脂。
