Fujifilm's Linear Tape-Open (LTO) Ultrium 7 produced with Barium Ferrite magnetic particles using Fujifilm's core NANOCUBIC technology. The Fujifilm LTO Ultrium 7 data cartridge offers a super high native/compressed storage capacity of 6.0/15.0TB, transfer rates up to 300/750MB per second, WORM capability and LTFS dual partitioning functionality to facilitate file management. Fujifilm's Barium Ferrite magnetic particles are chemically stable leading to enhanced performance and longer archival life. Fujifilm's LTO Ultrium 7 and future generations of LTO will use Barium Ferrite particles with NANOCUBIC technology for a thin and uniformly coated magnetic layer. Barium Ferrite is Fujifilm's patented technology.
TECHNOLOGY | Barium Ferrite Technology
Barium Ferrite is a type of magnetic particle which can be greatly reduced in size to improve recording density without magnetic signal loss. Barium Ferrite can maintain critical magnetic properties such as coercivity, frequency characteristics and lower noise even with a smaller particle size, resulting in the LTO Ultrium 7 cartridge having dramatically higher capacity compared to past generations of LTO cartridges.
Barium Ferrite is chemically stable (already oxidized) and does not get easily demagnetized by outside energy interference. Therefore, magnetic tape using Barium Ferrite can achieve a long archival life of more than 30 years based upon Fujifilm's accelerated life tests. With better frequency characteristics than metal particles, Barium Ferrite has a significantly increased margin of recording capability even when the ability of the drive head has diminished after repeated use.
