Product description

Graham Magnetics is proud to extend the life of these products and to make a significant positive impact on our environment. By giving these tapes a second life, Graham and its customers help save natural resources, use much less energy, and keep massive quantities of non biodegradable plastic and metals from our earth’s landfills.

We test every tape full length, on production drives to ensure performance per Industry Standards for new tape media. We are so confident in our testing process that all of our certified media is marked with the Graham Quality Trademark.

Labeled and Initialized Media
All 3590, 3590E, 3490 & 3480 cartridges can be labeled and initialized at the same time of purchase to work immediately with most popular operating systems. Performing this necessary step in the factory, saves your data center both time and money.

Characteristics of Certified Media
– Usable used media – 100% of old data removed prior to certification process
– All existing serial and library labels removed
– Each tape is physically inspected to assure performance characteristics are not compromised
– Each individual tape is certified with a binary test to assure high quality performance per our published specifications – to meet Industry standards for new tape
– Tapes that do not pass the rigorous Graham Magnetics requirements of physical and performance standards are degaussed and destroyed
– All tape media is packaged to provide the same shipping protection and appearance as new tape
– Each certified tape from Graham Magnetics is date stamped when tested

Using our certified cartridges saves customers significantly on media purchases, and since each cartridge is tested for damage as well as error activity, certified media is often reported to run ‘better than new.’ The only differences, besides the significant cost savings, the great Green Initiative contribution, is that the data center will notice a decrease in tape related problems.
