光学读取头 - If the optical head is on track , then the primary beam will be centered on a track ( with pits and bumps ) and the two secondary beams will be centered on land
如果光学头在轨道上，主激光束将处于轨道中心，两个副光束处于轨道之间。 - However , if the optical head is off track , then the center spot gets more light ( because there are fewer pits off track ) and the side detectors will be misbalanced
但是，如果激光头脱离轨道，中心光斑将得到更多的光（因为光斑照射到少量的坑形部分）并且附加探测器将失去平衡。
