一、薄型力矩器概述所谓的薄型力矩器主要是指用于标准高度为12.7mm的笔记本电脑光驱的力矩器,当然也包括用在小型移动装置上的力矩器。其主要作用与普通台式电脑光驱和DVD/VCD/CD播放机中的力矩器一样,即根据聚焦、循迹和倾斜误差信号实时地驱动物镜运动,使得聚焦光斑克服光盘的起伏振动等导致的光斑位置偏移,实现高质量的数据读写。其中,聚焦运动使物镜在垂直于光盘信息面的方向上移动,保证光斑精确地聚焦在盘片的信息表面上;循迹运动控制物镜在平
A thinner torque device Overview The so-called thin torque device is mainly used for the standard height of 12.7mm laptop optical drive torque converter, of course, including the use of small mobile devices on the torque converter. The main function is the same as that of a conventional desktop PC drive and DVD / VCD / CD player. That is, the objective lens is driven in real time according to the focusing, tracking and tilt error signals so that the focused spot overcomes the undulation of the optical disc and the like Position offset, to achieve high-quality data read and write. Among them, the focusing movement of the objective lens in the direction perpendicular to the information surface of the disc moves to ensure that the spot accurately focused on the disc surface of the information; tracking motion control objectives in the flat
