摘要： An optical disc manufacturing method suppresses thickness variation in intermediate layers disposed between any two data recording layers to achieve an intermediate layer of uniform thickness. A first step prepares a substrate 2 having a center hole 102 and data recording layer 1. This center hole is then plugged with a capping member 4 and a resin material 7 is dripped from above the center hole while spinning the substrate around its center hole to coat the data recording layer with the resin by a spin coating method. The capping member is then removed. Another step prepares a stamper 11 having a groove or lands and pits 10 on the surface. The groove or lands and pits side of the stamper is then pressed into the resin material on the substrate, and the resin is then cured to form an intermediate layer 17. The stamper is then separated from the substrate to leave a data recording layer 12 in the surface of the intermediate layer with a groove or land-and-pit pattern corresponding to the groove or lands and pits in the stamper.

摘要： When a separation layer is formed using a stamper between a substrate and the stamper on a thick substrate, on the surface of which a rewritable recording multilayer film provided with signal guide grooves or pits and the signal guide grooves or pits are transferred from the stamper to the surface, variations in the thickness of the separation layer are produced due to unevenness of the distance between the stamper and the substrate.
The surface of the kth signal recording layer 100 of the kth signal substrate 103 is shaped parallel to the surface with the guide grooves and pits 105 of the (k-1)th signal recording layer on the (k-1)th stamper 106, a (k-1)th separation layer 107 is formed between the two and then the (k-1)th stamper 106 is peeled off. The distance between the surface with the guide grooves and pits 105 of the (k-1)th signal recording layer and the kth signal recording layer 100 becomes uniform, and therefore the thickness of the (k-1)th separation layer 107 can be kept uniform.摘要翻译： 当在厚基板上使用基板和压模之间的压模形成分离层时，其表面上设有信号引导槽或凹坑的可重写记录多层膜和信号引导槽或凹坑从压模转移到 由于压模和基板之间的距离的不均匀，产生了表面，分离层厚度的变化。 第k信号基板103的第k信号记录层100的表面与第（k-1）信号基板103的第k信号记录层100的表面平行，第（k-1）信号记录层的引导槽和凹坑105， 在第二压模106之间形成第（k-1）个分离层107，然后第（k-1）个压模106被剥离。 第（k-1）信号记录层和第k信号记录层100的表面与引导槽的表面和凹坑105之间的距离变得均匀，因此第（k-1）个分离层107的厚度可以是 保持统一。

摘要： A transfer layer on a surface of a mold has a thickness distribution along the radius direction that the layer is thick in an inner round portion but is gradually thinner toward an outer round portion. An adhesive layer is formed between a surface of a signal substrate which bears a signal recording film and the mold which seats the transfer layer. The adhesive layer has a thickness distribution that the layer is thin in an inner round portion but is gradually thicker toward an outer round portion. Since the thickness distributions along the radius direction of the transfer layer and the adhesive layer are opposite to each other, the thickness distribution of an isolation layer which comprises the two layers is uniform.
