金銀?還是銅鋁?
真的有拿貴金屬做反射層嗎 
因為我的瞭解好像以前唱片所出的"黃金:紀念版 反射層都是"銅"(這是詐欺阿  )
而不是金色的就是拿鋁做反射層 而那些奇奇怪怪的顏色只是染料的顏色 |

KODAK CD-R Digital Audio Gold media has our proprietary SOUNDGUARD Protection System. We use a uniquely formulated dye to enhance low-speed recording and use a pure gold reflective layer to enhance environmental stability. And, our tough durability overcoat protects KODAK CD-R Digital Audio Gold discs from fingerprints and scratches.

is one in which gold is used in place of the super purity aluminium commonly used as the reflective coating on ordinary CDs.
The gold coats more evenly and reacts with oxygen slower, thus reducing CD rot and providing greater longevity.
The high fidelity usually associated with gold CDs is actually a result of the remastering process and not of the gold coating itself. Gold CDs can be played in any CD player.
