Look to archival grade DVD-R media to preserve your family photos and home movies as well as critical corporate data. Each disc is manufactured using Verbatims proprietary unique dual reflective layer technology which is comprised of a silver layer for broad compatibility and a gold layer for long archival life. The gold reflective layer, naturally resistant to corrosion, prevents oxygen from coming through the DVD bonding material and corroding the silver reflective layer. To further extend media lifetime, the DVDs contain a hard coating on the recording side to protect the discs from scratches.
