前一陣子在網路上看資料的時候
看到有文件提到
不同的Dye Formulation 也須要不同的pregroove 設計
但沒有任何比較詳細的討論
可不可以請您解說一下一些這方面的
design factor, 和 design trade off

染料的 refraction index
decompose 的體積變化
speed of decomposition

是我能想到的一些factor

希望您能教(開)導一下



例如:

"Different manufacturers use different dye technologies and phase change material. The pregroove design is optimised for each process and can therefore differ considerably. The phase change materials are fairly similar, but if a CD-RW disc is calibrated with a disc using one phase change material and pregroove design, and then measure a different disc using another phase change material and pregroove design, the measurement tolerances will be affected.
"

一些讀不太懂的reference
