1 前言在“CD-R生产中的染料光密度闭环控制”中,介绍了CD-R旋涂工艺过程中,利用ETA-DYE-ODPROCON系统保持光密度稳定性。随着可录光盘从CD-R到DVD-R的发展和读写速度的升高,染料层在槽内和岸上的微观分布的研究将越来越重要。生产者需要控制岸上的染料层厚度,因为它反映了盘片的光密度,同时为确保橙皮书参数规范,必须要控制槽内的染料层分布,其中包括了槽内的染料层厚度。下面以DVD-R为例,介绍染料层厚度分布对光盘质量的影响。然后介绍DVD-R染料层厚度分布在线控制系统:ETA-CD-I/DVD-R的测试结果。2 染料层厚度分布对橙皮书
1 INTRODUCTION In the CD-R Dye-Density Closed-Loop Control of CD-R Production, the use of the ETA-DYE-ODPROCON system to maintain optical density stability during a CD-R spin-on process is described. With the development of CD-Rs to DVD-Rs and the speed of reading and writing of recordable discs, the study of the microscopic distribution of dye layers in troughs and onshore will be more and more important. The producer needs to control the thickness of the dye layer on the shore because it reflects the optical density of the disk and to ensure that the parameters of the Orange Book parameter are controlled, the dye layer distribution in the tank must be controlled, including the dye layer thickness in the tank. The following DVD-R as an example, describes the thickness of the dye layer distribution on the quality of the disc. Then introduce the DVD-R dye layer thickness distribution on-line control system: ETA-CD-I / DVD-R test results. 2 dye layer thickness distribution on the orange book
