The MAM Archive CD-R is a high performance recordable disc, providing longevity and durability far in excess of conventional CD-R media. Every MAM Archive disc uses robust GoId-on-Gold® construction to provide the maximum resistance to environmental degradation. Long-term applications such as backfile conversion, e-mail archiving, and storage of classified correspondence can benefit from the Archive CD-R's strict quality control and patented Phthalocyanine dye (tha-lo-cy-a-neen) formula, which offers storage life well in excess of 100 years.  There is not a more stable, more reliable media for long term storage available today.  Only paper lasts longer.

What's the difference between Standard MAM Gold and Archive Gold? 

They are both produced on the same production lines, but the Archive gold is the "cream of the crop." We always sample from production to test quality, and sometimes the quality is exceptionally high (of course it's always within our specifications). At these times we pull the gold product, sampling it at a high frequency to ensure it's consistent high quality. This is what becomes Archive gold.
