反射層多半是鋁沒錯,隨著CD-R降價,貴金屬片早已絕跡,顏色多半由染料種類決定.重要的是染料本身化學特性如何,什麼顏色或含什麼金屬並不重要.
但商人了解,與其費時費力教育民眾化學,不如拿些簡單的'金啊!銀啊!'偽科學來騙人,簡單易懂又好騙錢.真的想深入了解碟片特性?花點時間讀化學吧!

....The materials used in CDs are all non-toxic -- polycarbonate plastic, gold or a silver alloy, an organic dye in the case of CD-R (which is related to that used in common photographic process), and a tiny amount of acrylic UV-cured lacquer are the only ingredients.....
