    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： 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.

    摘要： If a defective cluster in a spare area is managed with a defect entry, the size of a DFL will increase as the size of the spare area increases with an increase in the number of recording layers stacked in a disc. An information recording medium according to the present invention has pointer information indicating the location of the next available cluster in each spare area, and restricts the direction in which the spare area is used. Also, a defect entry indicating a defective cluster in the spare area is registered with the DFL. Thus, even if the size of the spare area 15 increases, the size of the DFL 21 can be kept relatively small. Furthermore, even after physical reformatting is done, a defective cluster, if any, in the spare area 15 can still be recognized as a defect and the control operation can be performed so that a replacement cluster is not re-allocated to that defective cluster (i.e., the defective cluster is not used).

    摘要翻译： 如果利用缺陷条目管理备用区中的有缺陷的簇，则随堆叠在盘中的记录层的数量的增加，随着备用区的大小的增加，DFL的大小将增加。 根据本发明的信息记录介质具有指示每个备用区域中下一可用簇的位置的指针信息，并且限制使用备用区的方向。 另外，用DFL登记表示备用区域中的缺陷簇的缺陷项。 因此，即使备用区域15的尺寸增加，DFL 21的尺寸也可以保持相对较小。 此外，即使在物理重新格式化之后，备用区域15中的缺陷簇（如果有的话）仍然可以被识别为缺陷，并且可以执行控制操作，使得替换簇不被重新分配给该缺陷簇（ 即不使用有缺陷的集群）。

    摘要： Performing sequential recording to alternate destinations of an information recording medium and improving access performance of accessing the information recording medium are achieved by estimating sequential defective areas of the information recording medium based on prescribed conditions, allocating blocks of a spare area as alternate destinations of the defective areas, and performing alternate recording to the allocated alternate destinations, in response to a recording request to record information to the sequential defective areas. The above can be achieved because the use of the alternate destinations will help to prevent a time-out from occurring due to he the defective areas.

    摘要： A display device of at least one embodiment of the present invention has a connection changeover circuit, including switch elements for time-division driving, formed on a liquid crystal panel, and the switch elements are paired so that two switch elements in each pair are connected in parallel to one video signal line. The paired switch elements are turned on at the same time, and immediately before one of the switch elements is turned off upon completion of a charging period for its corresponding video signal line, only the other switch element is turned off. As a result, while maintaining drive performance, it is possible to solve the impact of fieldthrough phenomenon caused by one of the switch elements, which are transistors, and also reduce parasitic capacitance formed in the other switch element, thereby suppress the impact of fieldthrough phenomenon caused by that switch element.

    摘要： To enable sequential recording to be performed to alternate destinations and improve in access performance, by controlling to estimate sequential defective areas such as bubbles based on prescribed conditions, allocate blocks of a spare area (15) as alternate destinations of these areas, and perform alternate recording to the allocated alternate destinations, in response to a recording request to the sequential defective areas, because when defective areas such as bubbles on a disk (1) exist so as to extend in a wide range, alternate recording in a single block unit frequently occurs in recording to these areas, thereby possibly causing time-out to occur.
