Verbatim UltraLife™ Gold Archival Grade DVD

Look to Verbatim UltraLife™ Gold Archival Grade DVD-R media to preserve your family photos and home movies as well as critical corporate data. Each disc is manufactured using proprietary unique dual reflective layers to maximize both compatibility and longevity. To further extend media lifetime, Verbatim UltraLife? DVDs contain a hard coating on the recording side to protect the discs from scratches.

Verbatim's proprietary dual reflective layer technology is comprised of a silver layer for broad compatibility and a gold layer for long archival life. The highly reflective silver layer allows the UltraLife™ DVD-R disc to look like a standard silver disc to DVD drives and recorders. This feature provides a low initial error rate after recording, important for long archival life, and the same drive read/write compatibility as standard silver-only discs.

The gold reflective layer, naturally resistant to corrosion, prevents oxygen from coming through the DVD bonding material and corroding the silver reflective layer. Silver oxidation can be a primary factor which limits the lifetime of DVD media.

The combination of MKMΓCOs patented Metal AZO DVD recording dye, revolutionary Dual Reflective Layer technology and proprietary hard coating enables Verbatim UltraLife? archival-grade DVD-R discs to deliver new levels in longevity and performance without sacrificing compatibility.

發文的時候還沒有...PCDVD...有點慢...

他的燒錄面不是金色的......

是不是金片是看反射層是否為金
而不是看燒錄面的顏色吧.... :jolin:

MAM-A是Mitsui子公司.....

那為什麼柯達的燒錄面是金的,而不是只有反射層而已?

染料顏色的差別

就像CD-R
金綠片是Cyanine + 金反射層 =>因為Cyanine顏色是水藍色，加上金的黃色就變成綠色

一般說的CD-R金片是Phthalocyanine + 金反射層
而Phthalocyanine是白黃色，加上金的顏色還是看起來像金色....

只是這樣的差別而已....
