摘要： In an information recording medium in which storage capacity per recording layer has increased so much that the size of an SBM varies with those of spare areas, there is mutual dependence between a DDS and an SBM and it is difficult to retrieve disc management information as intended. In an information recording medium according to the present invention, if the largest space is allocated to an user data area, the number of blocks to store a space bitmap is Ni (where Ni≧2). But if the smallest space is allocated to the user data area, the number of blocks to use is smaller than Ni. In such an information recording medium, if the number of blocks to store the space bitmap of a recording layer is Mi (where 1≦Mi≦Ni) and if Mi is equal to or greater than two, the space bitmap is divided into the 1st through Mith space bitmaps, each of which has a size that is still equal to or smaller than one block even when combined with a DDS, and each space bitmap is stored in an associated one of Mi blocks in a disc management area.
摘要翻译：在每个记录层的存储容量增加到SBM的大小随着备用区域的大小而变化的信息记录介质中，DDS和SBM之间存在相互依赖性，并且难以根据需要检索盘管理信息。在根据本发明的信息记录介质中，如果最大空间被分配给用户数据区，则存储空间位图的块数为Ni（其中，Ni≥2）。但是如果将最小的空间分配给用户数据区域，则使用的块数小于Ni。在这样的信息记录介质中，如果存储记录层的空间位图的块数为Mi（其中，1＆nlE; Mi＆nlE; Ni），并且如果Mi等于或大于2，则空间位图被划分为第1 通过Mith空间位图，即使当与DDS组合时，其每一个都具有仍等于或小于一个块的大小，并且每个空间位图被存储在盘管理区域中的相关联的一个Mi块中。

摘要： Minimized is the influence which is exerted by recording calibration (test recording) such as power calibration, strategy calibration or the like, performed in an area for recording calibration (recording calibration area or test area) provided in each of a plurality of recording layers, on recording calibration performed in the other recording layers.On a recording medium, data is recorded on at least one of a plurality of recording layers by laser light incident on a surface of the recording medium. The plurality of recording layers include a first recording layer, and second through N-th recording layers (N is an integer of 3 or greater) which are sequentially located in a direction from the first recording layer toward the surface on which the laser is incident. The plurality of recording layers each have a first calibration area and a second calibration area located outer to the first calibration area. The first calibration area located in each of the first through N-th recording layers is located at a different radial position from a radial position of the first calibration area in each of the other recording layers; and the second calibration area located in each of the first through N-th recording layers is located at the same radial position as a radial position of the second calibration area in each of the other recording layers.
