FUJIFILM Recording Media U.S.A. demonstrated the long term archivability of Barium-Ferrite (BaFe) magnetic tape particle, withstanding realistic storage environment simulations and proving its reliability over more than a 30 year time period.
"These findings show that the BaFe particle is not only a reliable tape storage solution because of its capacity but also for its proven long term reliability," said Peter Faulhaber, senior vice president of sales and marketing, FUJIFILM Recording Media U.S.A., Inc. "We have seen dramatic increases in the volume of data generated, transferred and stored today which has driven the need for increased, reliable storage media. Moreover, the solution must be able to stand up to the test of time in order for it to be a true value to IT professionals and storage managers."
To prove the long term reliability of its BaFe tape particle, Fujifilm used an accelerated environment evaluation (temperature 60?C, relative humidity 90%, 30 days) to confirm BaFe tape particle changes in demagnetization, friction coefficient and tape surface over time. In addition, a storage test in a polluted environment, known as a "Battelle experiment", was performed. Through this series of testing, it was proven that the data storage of 30 years or more with BaFe tape particle is possible and that the tape can maintain its magnetic characteristics for long term storage.
Employing its NANOCUBIC technology, Fujifilm succeeded in micro-particulation of the BaFe particle to 1600nm³, the equivalent of one-third of the current metal particle volume, uniformly dispersed and coated on a super smooth thin magnetic layer. This next generation version of NANOCUBIC technology uses a new ultra-fine, perpendicularly-oriented barium-ferrite magnetic medium that enables high-density data recording without using expensive metal sputtering or evaporation coating methods. Because Fujifilm?s new technology orients the particles in a perpendicular fashion and controls disposition at nanometer levels, it has also improved the tape?s running stability.
