摘要： An optical disk has a recording surface which is divided in the radial direction of the optical disk into a plurality of volumes. Each volume consists of a lead-in area, a program area and a lead-out area. Each of the volumes has a recording capacity which is not constant and has absolute position information recorded therein. The absolute position information consists of time information starting from a common initial value. The lead-in area, program area and lead-out area of the respective volumes is adapted to have information of the Compact Disc format recorded therein and adapted to have volume number information corresponding to the volume number thereof recorded in a predetermined position of the area. In one aspect of the invention, a part or all of the volumes has a higher recording density than a standard recording density determined by the Compact Disc format and absolute address information continuously increments from an initial value without overlapping among the respective volumes and address information is independent from the absolute address information. In another aspect of the invention, address information and absolute address information recorded in the first volume are within a range determined by the Compact Disc format and address information and absolute address information recorded in the second and subsequent volumes are larger than a value determined by the Compact Disc format.
摘要翻译：光盘具有在光盘径向分割成多个体积的记录面。每个卷包括导入区，程序区和导出区。每个卷具有不恒定的记录容量并且其中记录绝对位置信息。绝对位置信息由从公共初始值开始的时间信息组成。相应卷的导入区，节目区和导出区适于具有记录在其中的光盘格式的信息，并且适于具有与其中记录在该区域的预定位置的体积数相对应的体积号信息。在本发明的一个方面，一部分或全部卷具有比由压缩盘格式确定的标准记录密度更高的记录密度，并且绝对地址信息从初始值连续递增，而不在各卷之间重叠，而地址信息是独立于绝对地址信息。在本发明的另一方面，记录在第一卷中的地址信息和绝对地址信息在由光盘格式确定的范围内，地址信息和记录在第二卷和后续卷中的绝对地址信息大于由光盘格式。
