摘要： By avoiding the problem that in a hybrid optical disc with a standard-density recording area and a high-density recording area, an optical pickup designed to be suitable for the standard-density recording area cannot operate as desired in the high-density recording area and may cause a malfunction, damage to the disc drive or optical disc is prevented and optimal control is enabled. Access operation identification information such as reproducing identification information 225 indicating whether or not information recorded in the user data area 222 of the optical disc can be reproduced under the reproducing conditions of the optical disc driving apparatus is recorded in the lead-in area 222. The optical disc driving apparatus reads this type of access operation identification information, compares it with access operation identification information possessed by the optical disc driving apparatus, and if they do not correspond, does not carry out access operations by the optical head to the user data area 222, because reproducing or recording compatibility with the optical disc 201 is lacking.

摘要： An optical disc on which information can be recorded by recording light has a first recording layer (102) and a second recording layer (103) disposed behind the first recording layer as viewed by the recording light; the first recording layer and the second recording layer have respective power adjustment areas (P1, P2) that are used to adjust the power of the recording light to the optimal recording power at the time of recording of information on each recording layer; a prewrite area (PW) is provided in correspondence to the power adjustment area (P2) used for optimal power adjustment in the second recording layer and restricted areas (A1, A2) on both sides of that power adjustment area (P2). The restricted areas (A1, A2) allow for the diameter of the recording light beam and for lamination misalignment. This configuration enables stable test recording to be carried out in a short time on an optical disc having multiple recording layers.

摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

摘要： A first leakage current value output from each signal line is stored in a storage unit, with a charge corresponding to an emitted radiation being held in a radiographic image detector, when the radiation is uniformly emitted to the radiographic image detector. A second leakage current value is acquired which is output from each signal line, with a charge corresponding to the radiation dose being held in the radiographic image detector, when the radiation passing through an object is emitted to the radiographic image detector. When the first and second leakage current values are equal to each other for each line corresponding to each signal line, all pixels on the line are determined to belong to a background area (lines A and C). When the second leakage current value is smaller than the first leakage current value and larger than a predetermined value, it is determined that there are the object areas and the background areas on the line (lines B, D, and E), and the total number of pixels in the background area on the line is calculated from the ratio of the first leakage current value to the second leakage current value. In this way, the distribution of the object area and the background area in the image which is held in the radiographic image detector when the radiation passing through the object is emitted is estimated before the reading of the image from the radiographic image detector is completed.
摘要翻译：当辐射被均匀地发射到放射线照相图像检测器时，从每个信号线输出的第一泄漏电流值被存储在存储单元中，其中对应于发射的辐射的电荷被保持在放射线照相图像检测器中。当通过物体的辐射被发射到射线照相图像检测器时，获取从每个信号线输出的第二泄漏电流值，其中对应于辐射剂量的电荷被保持在放射线照相图像检测器中。当对于每个信号线的每一行的第一和第二泄漏电流值彼此相等时，该行上的所有像素被确定为属于背景区域（行A和C）。当第二漏电流值小于第一泄漏电流值并且大于预定值时，确定在线（线B，D和E）上存在物体区域和背景区域，并且总共根据第一泄漏电流值与第二泄漏电流值的比率，计算线路背景区域中的像素数。以这种方式，在从放射线照相图像检测器读取图像完成之前，估计当通过物体的辐射被发射时保持在放射线照相图像检测器中的图像中的对象区域和背景区域的分布。
