 "Verbatim UltraLife Gold Archival Grade - CD-R x 5 700 MB storage media" " Verbatim media 96319 CD-ROM Media CDW.com
"Verbatim's proprietary dual reflective 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 CD-R disc to look like a standard silver disc to CD burners. This feature provides a low initial error rate, important for long archival life, and the same drive read/write compatibility as standard silver-only discs.The gold reflective layer is naturally resistant to corrosion. The gold layer overlaps the silver layer and prevents oxygen from coming through the lacquer layer or edge of the disc and corroding the silver. Silver oxidation can be a primary factor which limits the lifetime of CD media."
