速度是光盘生产的根本,但最终的检测工艺也同样重要,所有的盘片都需要检测。对于通常的光盘生产周期,最终盘片检测应在2秒左右判断出盘片是否合格。对于 DVD 和 CD-R 情况略有不同,甚至更具挑战性。当 CD 光盘涂布保护胶工艺或 DVD 光盘粘合工艺结束后,光盘的物理生产已经完成。此时,大多数生产者都想知道生产的盘片是否合格,需要进行检测。而在印刷、包装后,表面缺陷就会被掩盖。
Speed is the root of CD production, but the final detection process is equally important. All the disks need to be tested. For the usual disc production cycle, the final disc test should be about 2 seconds to determine whether the disc is qualified. It’s even more challenging for DVDs and CD-Rs to be slightly different. The physical production of the disc has been completed when the CD-ROM is coated with a protective glue process or the DVD disc bonding process is completed. At this point, most producers want to know the production of the disc is qualified, need to be tested. In the printing, packaging, surface defects will be covered.
