1．引言可记录光盘(CD-R,DVD±R)可视为一个多层膜系组成的光学系统。信息层(染料层)是其中的关键:控制难度最大,对盘片最终质量影响最大,因为所有的最终用户数据将记录在信息层上。随着可记录光盘媒质技术的发展,盘片记录密度越来越小(从CD-R,DVD-R,到DVR),盘片的读写速度越来越高(CD-R记录速度从1x,2x到48x,52x;DVD-R记录速度从1x,2x到8x,下一步到16x),染料层也由
1. Introduction CD recorders (CD-R, DVD ± R) can be considered as a multi-layer optical system. The information layer (dye layer) is one of the key points: control is the most difficult and has the most impact on the final quality of the disc, as all end-user data will be recorded at the information level. With the development of recordable disc media technology, the disc recording density becomes smaller and smaller (from CD-R, DVD-R to DVR), the reading and writing speed of the disc is getting higher and higher (CD-R recording speed is from 1x , 2x to 48x, 52x; DVD-R recording speed from 1x, 2x to 8x, next to 16x), the dye layer also consists of
