1.前言在光盘记录中,一束会聚激光穿过感光胶层聚焦在记录层上,这样,信息沿着凹槽被记录下来(如图1所示)。由光记录保证高记录2.测量系统 (1)有关测头设计的研究测头应具有良好的追迹性能,物镜沿轴向和径向应平行移动。而且测头应具备足够的宽度变化范围用于测量直径为130Inm的光盘。
1. INTRODUCTION In disc recording, a convergent laser beam is focused through the photo resist layer onto the recording layer so that information is recorded along the groove (as shown in Figure 1). High Record by Optical Recording 2.Measurement System (1) Research on Probe Design The probe should have good tracking performance and the objective lens should move parallel in the axial and radial directions. And the probe should have sufficient width variation range for measuring discs with a diameter of 130 mm.
