MAM-A DVD-R 4.7GB NO-LOGO GOLD 50SPN 8X
The MAM Gold Archive Grade™ DVD-R is designed for applications requiring long-term storage of sensitive data, video or music files. The reflective layer is comprised of 24 karat gold, which allows maximum resistance to chemical breakdown -- one of the major causes of disc failure. Along with choosing the right recording dye material and bonding agent (Note: A DVD-R is made of two polycarbonate discs bonded together) the long-term stability of the reflective layer is crucial. Reflective layers using your standard "silver" surface are subject to oxidation (rust) over a long period of exposure to moisture. Unlike silver jewelry, a gold ring won't rust and neither will the gold reflective layer in this disc. In optical discs, the use of gold can triple the life of a standard disc. 
MAM-A Gold vs. Silver media
The above chart shows 2 silver DVDs that have failed in less than 500 hours and another silver DVD that did much better, but the MAM gold DVD still has error rates well below the upper limit of 28D. At this pace, MAM is expecting a lifetime of over 100 years.
