UltraLife™ Gold Archival Grade DVD-R 4.7GB 8X 50pk Spindle

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 MKM’s 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.
