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： An apparatus is provided for searching for a writable area of a write-once information recording medium, comprising a searching portion and a control portion. The searching portion searches for an unrecorded area using a prescribed address as a reference. The control portion provides a candidate address indicating a candidate for a writable area based on a result of the search, and performs a determination procedure for determining whether or not there is a defective area address indicating an address matching the candidate address in defect management information. When it is determined that there is not the defective area address indicating an address matching the candidate address, the control portion determines an area indicated by the candidate address as the writable area.

摘要： An information recording apparatus is provided with a recording controller for recording data on an information recording medium, a verification controller for verifying whether or not the recorded data can be correctly reproduced, a continuous recording controller for providing a gap region of a specified interval between a verification region and a recording region and successively performing a verify processing and a record processing with rotation waiting in between, an error region discriminator for discriminating an error region in the event of an error in the process of performing the verify processing and the record processing, and an error processor for performing an error processing according to the error region. The error processor performs an error processing different from the one performed when an error occurred in either one of the verification region and the recording region if an error is discriminated to have occurred in the gap region. By this construction, a recording time is shortened and it is prevented that data cannot be recorded on the information recording medium.
