Long-Term Stability of Data Storage Tape－Acceleration test under hot condition－

Abstract

The long-term stability of magnetic particulate tapes (LTO and a more modern barium ferrite data cartridge tape) was investigated using samples that had been stored under 60 °C/Dry condition for one year. Expansion of the storage period of the samples stored under the above conditions by 10 times resulted in the same degradation trends as those of the LTO samples that had been aged in an office environment. The same procedure was applied to a more modern barium ferrite tape. The degradation of the barium ferrite tape was equal to or less than that of the LTO tape. Thus, the 1-year acceleration test showed that the stability of LTO and the barium ferrite tape could be estimated to be more than 10 years.
