摘　　要：合成了一种ＣＤ－Ｒ用菁染料，测定了该染料溶液的吸收光谱，薄膜的吸收、透过和反射光谱。测定了用该染料制成的光盘在不同记录功率和记录频率下，不同记录速度的载噪比（ＣＮＲ）。结果表明，该染料能与相应ＣＤ－Ｒ刻录机的半导体激光器（７８０ｎｍ）很好地匹配，在合适的记录条件下，各种记录速度均有较高的载噪比。The cyanine dye for CD recordable has been synthesized and its absorption in solution and absorption and reflection spectra for its thin film have been measured. The carrier to noise ration (CNR) at various recording rates for the CD R disc made with the dye have been tested at different recording powers and frequencies. The dye synthesized in this paper shows a good performance for CD R. When recorded on 780 nm laser, the dye gets higher CNR with 2 up 4 times recording rates.
