摘要： An optical pickup which, when a first light reflected by a recording medium is divided into a central light area and first and second peripheral light areas at both sides of the central light area, divides the first light reflected by the recording medium into at least 6 light areas, and the at least 6 light areas are independently detected from first through sixth light-receiving portions of a photodetector. Hence, the photodetector can detect a tracking error signal whose offset generation due to a shift of an objective lens is insensitive and whose offset generation due to an initial photodetector balance deviation is depressed.
摘要翻译：一种光拾取器，当由记录介质反射的第一光被分成中心光区域和中心光区域两侧的第一和第二周边光区域时，将由记录介质反射的第一光分成至少6个光区域，并且至少6个光区域被独立地从光电检测器的第一至第六光接收部分检测。因此，光检测器可以检测由于物镜的偏移引起的偏移产生不敏感并且由于初始光电检测器平衡偏差导致的偏移产生被抑制的跟踪误差信号。
