摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

摘要翻译： 在具有符合多个不同光盘标准的信息层的多层光盘中，由于每个信息层的类型不被记录在其他信息层中，所以在兼容的光盘装置的读写操作中，符合多个 光盘标准，每次被访问的信息层都改变时，必须读取信息层的类型，并选择一种生成适合于信息层类型的跟踪误差信号的方法，因此访问需要时间。 为了解决上述问题，在根据本发明的具有符合多个不同光盘标准的信息层的光学多层盘中，在信息层之一中的区域中记录关于其他信息层的信息 。 可以通过使用该信息来选择跟踪误差信号生成方法来减少访问其他信息层所需的时间。
