摘要： A multi-layered optical disk has three or more recordable or rewritable information recording layers including at least a first recording layer and a second recording layer located on the side nearer to the light incident surface than the first recording layer, a first test area configured by a plurality of segments in the first recording layer and a second test area configured by a plurality of segments in the second recording layer. The disk further has a specific area in which there is recorded information used to determine whether or not the respective segments in the first test area can be used. The purpose of this arrangement is to enable recording in securing sufficient test areas without reducing user data areas, and suitably controlling the power of laser beam irradiated onto each of the layers. It is thereby possible to improve the quality of recording and the reliability of the recorded data.

摘要： To provide a recording method of a multilayered optical disk having three or more recording layers, for performing recording while securing sufficient test areas without reducing user data areas, and while suitably controlling the power of laser beam irradiated onto each of the layers. The method uses an optical disk which has at least a first recording layer and a second recording layer located on the side nearer to the light incident surface than the first recording layer, and which respectively has a first test area configured by a plurality of segments in the first recording layer and a second test area configured by a plurality of segments in the second recording layer. Further, the method is configured such that there is defined beforehand a predetermined radial distance L corresponding to relative precision of radial positions between the plurality of layers and the optical spot diameter, and that when an arbitrary segment in the second test area is test-recorded, a segment in the first test area, the radial distance of which from the recorded test area in the second test area is within the range of the predetermined radial distance L, is set as a segment in which the test recording is not performed. Thereby, even in the case where the radial positions of the test areas of the plurality of layers are substantially overlapped with each other, it is possible to precisely perform the learning of optical power. For this reason, it is possible to use and arrange the test areas of the plurality of layers without waste. Further, the learning of recording power can be performed without receiving the influence of the recorded state of the other layers, so that the accuracy of the learning of recording power can be improved. Thereby, it is possible to improve the quality of recording and the reliability of recorded data.
摘要翻译：为了提供具有三个或更多个记录层的多层光盘的记录方法，用于在确保足够的测试区域的同时确保足够的测试区域而不减少用户数据区域，并且同时适当地控制照射到每个层上的激光束的功率。该方法使用至少具有第一记录层和位于比第一记录层更靠近光入射面的一侧的第二记录层的光盘，并且分别具有由多个区段构成的第一测试区域第一记录层和由第二记录层中的多个段构成的第二测试区。此外，该方法被配置为使得预先确定对应于多个层之间的径向位置与光点直径的相对精度的预定径向距离L，并且当第二测试区域中的任意段被测试记录时第一测试区域中的第二测试区域中从记录测试区域的径向距离在预定的径向距离L的范围内的段被设置为不执行测试记录的段。因此，即使在多个层的测试区域的径向位置彼此大致重叠的情况下，也可以精确地执行光功率的学习。因此，可以不浪费地使用并排列多层的测试区域。此外，可以在不接收到其他层的记录状态的影响的情况下执行记录功率的学习，从而可以提高记录功率的学习的准确性。由此，可以提高记录质量和记录数据的可靠性。

摘要： Where a hybrid disc has different types of media, the light spot moves among recording layers of the different media, after loading the disc into an optical disc apparatus, there is a problem that information on a media type of each recording layer should be recorded in DI etc. of the optical disc (100). Detailed information on the hybrid disc is stored in DI, by changing a disc layer type identifier or a disc structure in DI such as BCA or PIC on the optical disc (100).

摘要： A recording medium, an address generating method, an address detection method and a recording and reproduction apparatus capable of extending the wobble address without any considerable wobble restructuring are disclosed. Virtual bits not recorded in the disc and expressed by the difference of the rule or the presence or absence of the information embedded in a part or the whole of the wobble address are generated. Thus, the extended address can be obtained without changing the number of bits of the address embedded in the wobble.
