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： 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.

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. 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。如果写入脉冲的脉冲宽度或脉冲位置以1T / n的精度定义（其中T是通道时钟脉冲宽度，n是正整数），则偏移值的大小足够大以至少定义一个n / 2范围。
