用于光盘的信息复制材料及其在温度场中的稳定性

STUDY ON INFORMATION-DUPLICATED MATERIAL FOR CDsAND ITS STABILITY IN TEMPERATURE FIELD

选择丙烯酸酯基固化膜作为光盘信息复制材料，测量了其在７８０ｎｍ处的吸收系数，并进行了ＴＧＡ和ＤＳＣ热分析根据热吸收理论，计算了ＲＯＭ光盘膜层中由激光辐照引起的温度场分布，结果表明，信息复制层在温度场中只有较高的稳定性。

n this paper, curable acrylate polymer is selected as the information-duplicated mainal for CDs, its absorption coefficient at 780nm is measured and thermal analyisis such as TGA and DSC is also held. With the theory of heat absorption, the temperature field distribution caused by laser radiation is computed based on the typical CD-ROM structure, and results shows that the duplicatd layer has high stability in the temperature field.
