REV PRO tEchnical guidE
guaranteed archival lifespan
The REV PRO media long-term archival rating is speci-
fied to over 30 years. The engineers designed RRD tech-
nology to ensure long shelf life by identifying the causes
of long-term media degradation and engineered REV
PRO to minimize those specific effects. Normal factors
of long-term media degradation include thermal stability,
self-demagnetization, media corrosion, motor or connec-
tor failure, particulate infiltration, contamination, out-gas-
sing, and adhesive breakdown. All of these factors have
been addressed and dealt with for REV PRO.
To prevent issues of adhesive breakdown, REV PRO car-
tridges use only high-quality, HDD-approved adhesives
for mounting the internal desiccant and filter inside the
cartridge housing. The adhesive is rated for continuous
80ºC (176ºF) conditions.
Unlike REV PRO media, videotape can deteriorate rap-
idly over time as a result of exposure to oxygen, atmo-
spheric moisture, and heat—a process called hydrolysis.

Even at constant 70˚C (158˚F) temperatures, REV PRO media decays less than 1% every
ten years.
