Barium Ferrite

About Barium Ferrite

  • Barium Ferrite is a new type of magnetic particle which can be greatly reduced in size to improve recording density without magnetic signal loss.
  • Fujifilm's LTO 6 and later generations of LTO will use Barium Ferrite particles with NANOCUBIC technology for a thin and uniformly coated magnetic layer.
  • This is Fujifilm's patented technology!
  • Barium Ferrite is already used and proven in enterprise products such as StorageTek's T10000C tape cartridge.

Higher capacity

Regular metal particle (MP) is approximately 40 -100nm whereas Barium Ferrite is approximately 20nm*1. The smaller size enables much higher recording density resulting in super high capacity data cartridges.

Long archival life

Oxidization is one of the causes of data deterioration. However, Barium Ferrite is already oxidized and therefore has a much longer life compared to metal particles (MP). While LTO drive systems are recommended for upgrade every 10 years, the road map is purely hardware manufacturer dependent, so longer archival life is preferred.

Recording stability

Barium Ferrite has better frequency characteristics compared to metal particles (MP) resulting in a significantly increased margin of recording capability. Therefore, it is expected that Fujifilm LTO6 and later generations can be written to and read even when the ability of the drive's recording head has diminished after repeated use.
