摘要： An information recording medium according to the present invention includes three or more information recording layers. Each of the plurality of information recording layers includes a test recording area usable for adjusting a recording condition. One of the plurality of information recording layers includes a reproduction-only management data area in which management data usable for managing the information recording medium is pre-recorded. One information recording layer includes a recordable management data area in which management data usable for managing the information recording medium is newly writable. Each of the other two or more information recording layers among the plurality of information recording layers includes a test recording area at a radial position overlapping the radial position of a part of the reproduction-only management data area. In the one recording layer including the recordable management data area, the recordable management data area is provided at two positions, i.e., one on the inner side and the other on the outer side to the test recording area.

摘要： The present invention provides a measure for getting read/write control information stored within a space of a predetermined size in a format that ensures compatibility with media of a lower order or an older generation even if the size of the read/write control information increases significantly as the storage densities of information storage media rise in the near future. On an information storage medium, a data sequence is writable as a combination of marks and spaces. The medium has at least one information storage layer, which has an information storage area to store information and a control information area for use to perform a read/write operation on the at least one information storage layer. The control information area stores at least one set of control information, which includes a first kind of write pulse information including information to be used as a reference value and a second kind of write pulse information including information to be used as an offset value. The size of the offset value is at least a half as large as that of the reference value.
摘要翻译：本发明提供一种用于获得存储在预定大小的空间内的读/写控制信息的措施，即使读/写控制信息的大小显着增加，也可以确保与较低级别或较老版本的媒体兼容的格式随着信息存储媒体的存储密度在不久的将来上升。在信息存储介质上，作为标记和空格的组合可写入数据序列。介质具有至少一个信息存储层，其具有用于存储信息的信息存储区域和用于对至少一个信息存储层执行读/写操作的控制信息区域。控制信息区域存储至少一组控制信息，该组控制信息包括包括要用作参考值的信息的第一种写入脉冲信息和包括要用作偏移值的信息的第二种写入脉冲信息。偏移值的大小至少是参考值的一半。

The control information area stores at least one set of control information, which includes a first kind of write pulse information including information to be used as a reference value and a second kind of write pulse information including information to be used as an offset value. If the pulse width or pulse position of a write pulse is definable with a precision of 1T/n (where T is a channel clock pulse width and n is a positive integer), the size of the offset value is large enough to define at least an n/2 range.

摘要： A recording type optical disk on which data is recordable includes a data recording and reproducing area for recording data therein and reproducing data therefrom, and a read-only disk identification information area for recording disk identification information for identifying the optical disk therein. In the optical disk, the disk identification information is formed by removing a reflection film that is formed on the optical disk in a strip shape. The disk identification information includes an inherent disk identifier for each optical disk, and the data recording and reproducing area includes an area for recording encrypted data therein. The encrypted data is encrypted by using information including the disk identification information for identifying the optical disk as a key.
