A high precision feed table and control system were developed to drive the optical head in a disc mastering device.
为实现母盘刻录机中光学头的精密进给，研制了精密微进给工作台及其伺服控制系统。
Thus the size of the optical head is greatly reduced, and simultaneously the amount of light is adjusted with high accuracy and high sensitivity.
这样，在追求光学头的大幅小型化的同时，还可以实现更高精度和灵敏度的光量调整。
