UltraLife 52x CD-R Media preserves your family photos and important records as well as critical corporate data. Each disc is manufactured using proprietary unique Dual Reflective Layers (DRL) to maximize both compatibility and longevity.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.
