Verbatim DVD-R UltraLife Gold Archival Grade 4.7GB Recordable Disc (Pack of 5)
The Verbatim DVD-R UltraLife Gold Archival Grade 4.7GB Recordable Disc (Pack of 5) is a write-once disc designed to preserve family photos and home movies as well as critical corporate data. Each disc is manufactured using single reflective layer to maximize both compatibility and longevity. To further extend media lifetime, there is a hard coating on the recording side to protect the discs from scratches. The disc uses a Metal Azo DVD recording dye optimizes read/write performance.
Single layer technology is comprised of a gold layer for long archival life. 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.
