摘要： In an optical recording method, recording parameters (WU) to be used for recording are obtained using recommended recording parameter values (WR) read from an optical recording medium and previously obtained vector information (PC) and approximation coefficients (Ca, Cb) (S24). Writing to the optical recording medium is performed using the obtained recording parameters (S17). The vector information (PC) includes a vector component of the parameters obtained statistically with respect to parameter difference values (DF) between optimal recording parameter values (WO) and the recommended recording parameter values (WR) over a plurality of optical recording media so as to strengthen mutual correlation between the parameters. The approximation coefficients (Ca, Cb) are obtained by approximating a relationship between converted information (X) and feature information (D), the converted information (X) indicating a relationship between the vector information (PC) and the parameter difference values (DF), the feature information (D) indicating the features of each optical recording medium obtained from the recommended recording parameter values (WR) and the vector information (PC).

摘要： In an optical pickup device, a flexible substrate (FPC) (2) and an auxiliary board (4) are fixed to an optical unit (5) with screws (11) before fixing an optical detector (1) to the FPC (2). After that, the optical detector (1) is pressed to the FPC (2) by probes (12), to bring lead portions (1a) into contact with conductor portions (2a). The optical detector 1 is singly moved by the probes (12) in that state, to perform position adjustment of the optical detector (1). Since the friction between the optical detector (1) alone and the FPC (2) is small, the position adjustment can be performed with high accuracy. Further, since the lead portions (1a) and the conductor portions (2a) are in contact with each other, it is possible to perform the position adjustment while observing an electrical signal outputted from the optical detector (1) through the FPC (2). Then, after determining the optimal position of the optical detector (1), the lead portions (1a) and the conductor portions (2a) are fixed to each other by soldering. Through such a manufacturing method, it is possible to improve the accuracy of position adjustment of the optical detector relative to the optical unit and improve the reliability of position of the optical detector after the position adjustment.
摘要翻译：在光拾取装置中，在将光学检测器（1）固定到FPC（2）之前，通过螺钉（11）将柔性基板（FPC）（2）和辅助板（4）固定到光学单元（5）。之后，通过探针（12）将光学检测器（1）按压到FPC（2），以使引线部分（1a）与导体部分（2a）接触。在该状态下，光检测器1被探针（12）单独移动，以进行光检测器（1）的位置调整。由于单独的光学检测器（1）和FPC（2）之间的摩擦小，因此可以高精度地执行位置调整。此外，由于引线部分（1a）和导体部分（2a）彼此接触，所以可以通过FPC观察从光学检测器（1）输出的电信号来执行位置调整（ 2）。然后，在确定了光学检测器（1）的最佳位置之后，引线部分（1a）和导体部分（2a）通过焊接彼此固定。通过这样的制造方法，能够提高光检测器相对于光学单元的位置调整精度，提高位置调整后的光检测器的位置的可靠性。

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.
