摘要

常見的CD-R或DVD-R光碟片其寫入資料前後之反射率皆是由高到低（High-to-low）的變化，在本研究中我們採用一般市面上常見的CD-R染料（Super-Green）成功地做出了資料寫入前後反射率由低到高變化（Low-to-high）的新型態DVD-R光碟片。
在實驗中，我們藉由改變染料膜厚、基板溝軌深度、反射層材料及寫入功率等參數，來探討其對於此新型態DVD-R光碟片之特性有何影響，並採用DVD碟片動態測試機、光學膜層模擬軟體、原子力顯微鏡、光學密度測試儀來驗證Low-to-high現象之發生，並探討其發生機制。由實驗中我們歸納出較適合此新型態Low-to-high光碟片的製程參數，而且得到的CNR值可達到一般DVD-R光碟片基本要求的物理特性值（CNR≧45dB）。

The commercial recordable compact disc (CD-R) and recordable digital versatile disc (DVD-R) have the high-to-low change in reflectivity before and after recording. We adopt the commercial dye (super-green) for CD-R to produce the DVD-R disc and the reflectance has the low-to-high phenomenon.
In this study, we probed into the effect of the low-to-high DVD-R by varying the optical density, writing power, reflective layer and the groove depth of the substrate. To understand the phenomenon of the low-to-high polarity, we test the experimental disc by using the DDU-1000, optical density tester (ETA-RT), atomic force microscope (AFM) and the thin film design software (TFCalc). We also generalize a better parameter for manufacturing the low-to-high DVD-R disc. And the CNR value of the disc can satisfy with the requirement of the DVD-R media (CNR≧45dB).
