BaFe Recording characteristics High Output Supports High Density Recording

Output Signal to Noise Ratio (SNR) of BaFe particle tape is far better than that of MP (G5) tape enabling higher linear density and recording capacity.

Frequency characteristics Barium Ferrite has better frequency characteristics compared to metal particles resulting in a significantly increased margin of recording capability. Therefore, it is expected that Fujifilm LTO 6 can be written to and read even when the ability of the drive’s recording head has diminished after repeated use.
