摘要： An object of the present invention is to attain stable tracking servo performance by suppressing an offset caused by a shift of an object lens or a tilt of a disk, despite the one-beam method which does not cause reduction in light quantity of the main beam. A diffraction grating is provided between a hologram and a light receiving section, and a diffraction efficiency of the diffraction grating is varied in a grating longitudinal direction. For example, if an incident light beam on the diffraction grating is shifted in the grating longitudinal direction, the quantity of received light in each light receiving section varies to cause offset. By performing tracking servo so as to cancel the change, it is possible to correct the offset, thereby attaining stable tracking servo performance.
摘要翻译：本发明的目的是通过抑制由于物镜的偏移引起的偏移或盘的倾斜而获得稳定的跟踪伺服性能，尽管不会导致主光束的光量的减小的单光束方法。在全息图和光接收部之间设置衍射光栅，衍射光栅的衍射效率在光栅长度方向上变化。例如，如果衍射光栅上的入射光束在光栅长度方向上移动，则每个光接收部分中的接收光量变化，导致偏移。通过执行跟踪伺服以消除变化，可以校正偏移，从而获得稳定的跟踪伺服性能。
