摘要： In a method for manufacturing a master disc for optical discs, patterns to be displayed on the disc are classified into a main object and a background. The background is commonly assigned as the background pattern for glittering rainbow colors by diffracted light reflected from dummy pits of diffraction gratings or a hologram. The main object is individually assigned as the main object pattern of a diffused reflection portion or mirror surface. The manufacturing method comprises one group of steps for forming the common background pattern and the other group of steps for forming the individual main object pattern in the common background pattern. A development substrate for the master disc is formed by using a mask disc in a first light-exposure of a photoresist layer thereof and by using a displaying-pattern mask in a first light-exposure of the photoresist layer. The individual main object pattern is drawn in the common background pattern of the master disc by using a laser-marking or an etching. The mask disc and displaying-pattern mask can be used repeatedly as families for the background and main object patterns so as to facilitate the replication of the optical discs.
摘要翻译： 在用于制造用于光盘的母盘的方法中，要在盘上显示的图案被分类为主要对象和背景。 背景通常由衍射光栅或全息图的虚拟凹坑衍射的衍射光指定为闪烁的彩虹色的背景图案。 主要物体被单独地分配为扩散反射部分或镜面的主要对象图案。 该制造方法包括用于形成公共背景图案的一组步骤和用于在公共背景图案中形成单独主要对象图案的另一组步骤。 通过在其光致抗蚀剂层的第一次曝光中使用掩模盘并且在光致抗蚀剂层的第一次曝光中使用显示图案掩模来形成用于母盘的显影衬底。 通过使用激光标记或蚀刻将单个主要对象图案绘制在母盘的公共背景图案中。 掩模盘和显示图案掩模可以重复地用作背景和主要对象图案的系列，以便于光盘的复制。

摘要： An optical disk with multi-layered structure provided with at least two recording layers is provided. In respective recording layers, tracks are formed, and the track is formed such that the amount of eccentricity is different in respective recording layers. In the method for identifying the recording layer which identifies the recording layer of the optical disk, the recording layer is identified by detecting the amount of the eccentricity set to the track of the respective recording layers.
