ODC母盘刻录系统的光路介绍与刻录激光器的更换

The introduction of optical circuit of ODC mastering system and how to change laser beam recorder

ODC母盘系统的刻录方式与特点在传统母盘刻录方式下,坑槽的形成是采用某些对光敏感的物质,在激光的照射下其化学性质发生改变,能被一些特殊配置的碱性溶液溶解。其过程称作曝光、显影,是化学过程。在ODC母盘刻录方式下,其坑槽的形成的原理是:物质有三态,大多数的物质随着温度的逐渐升高,可由固态转化为液态,再从液态转化为气态。其中有些特殊物质对温度极其敏感,当温度到达临界点时,几乎没有经过液态或液态极短。

It introduces the laser recording part of ODC mastering system, change of laser, adjustment of optical circuit, relative equipment and instrument. Also it emphasizes the noticeable problems during operation. It will be helpful for customers who are using ODC mastering system.
