Overview
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 manage-ment. 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.
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 demagne-tized 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.
High Capacity and Transfer Rates
Fujifilm’s NANOCUBIC technology has enabled LTO Ultrium 7 to achieve a native/compressed capacity of 6.0/15.0TB by recording 3,584 data tracks within 12.65mm tape width. With the utilization of multi-channel recording technology, LTO 7 features native/compressed transfer rates of up to 300/750MB per second.
Reel Design
As the tape length increases, there is a tendency of increased pressure on the hub with the potential risk of causing hub deformation. This may lead to potential problems, such as tape edge damage or other physical anomalies. In
order to avoid such hub deformation, Fujifilm has strengthened the hub structure by applying a new design with new materials. As a result, Fujifilm has successfully achieved both running stability in the drive and a highly reliable archival
life expectancy.
Environmentally Friendly
BFR (brominated flame retardants) have been eliminated from all LTO 7 mechanical parts in order to become more environmentally friendly.
