摘　　要：1 前言近年来,光存储技术飞速发展,可写光盘(CD-R/DVD-R)作为可记录信息载体得到广泛的应用。可写光盘的复制工艺包括模压(基片)、旋涂(染料层)、溅镀(反射层)、涂保护胶(保护层)几个部分,图1显示了CD-R的多层膜结构。可写光盘的基片材料为聚碳酸酯,用注塑法成型,在成型同时复制出沟槽;染料层用旋转涂膜法制备;反射层由银靶或金靶用溅镀法制备;保护层一股采用UV树脂,用旋涂法成膜。Optical characteristics of dye film are studied,which is based on optical multi-layer film theory and dye materials characteristics of recordable disc.The simulated n-k-T curve gives reference to development on dye materials.The liner relationship between Optical Density at different measured wavelength and film thickness is analyzed.Design method of dye thickness on land and dye thickness in groove of recordable disc is introduced.
