Fujifilm together with IBM Answers to Sony
Native 154TB into LTO cartridge
Citing its use of proprietary NANOCUBIC and Barium Ferrite
(BaFe) particle technologies, FUJIFILM Corporation, announced that in
conjunction with IBM Corp., a record in areal data density of 85.9 billion bits
per square inch on cost-efficient linear magnetic particulate tape has been
This breakthrough in data density equates to a standard LTO
cartridge capable of storing up to 154TB of uncompressed data, which is 62 times
greater than today's
current LTO-6 cartridge capacity.
This record was reached using an advanced prototype tape
incorporating NANOCUBIC technology developed by Fujifilm, with advanced
tape-drive technologies developed by IBM.
Fujifilm's research addresses previous shortcomings associated
with decreasing the magnetic particle size and thermal stability degradation.
The enhanced NANOCUBIC technology decreases the BaFe magnetic particle volume,
which is essential for high density data recording, while maintaining its
thermal stability to ensure long term archivability of recorded data.
Since the surface roughness of tape is directly related to
both signal-to-noise ratio and high quality output, NANOCUBIC technology
incorporates NANO coating and dispersion techniques to control surface
smoothness. In addition, NANO perpendicular orientation precisely aligns the
BaFe particles to produce high quality read signal over a wide frequency.
Fujifilm Proprietary Media Technology
- Enhanced NANO particle: The new BaFe synthesis method
decreases the particle volume while maintaining its thermal stability by
suppressing the distribution of the particle size and the magnetic
properties. The technology creates a uniform NANO particle with consistent
- Enhanced NANO coating and dispersion: The new dispersion
process and dispersion material make it possible to separate each BaFe
particle and avoid the agglomeration of fine BaFe particles. The uniformly
dispersed BaFe particles form a thinner magnetic layer with an extremely
smooth surface. These technologies lead to improved signal-to-noise ratios
and high frequency responses, and eliminate the need for expensive metal
sputtering or evaporation coating methods.
- NANO perpendicular orientation: This new technology
allows the aFe particle orientation to be precisely controlled by taking
advantage of the magnetocrystalline anisotropy of BaFe to deliver a high
quality read signal over a wide frequency.
Collaboration with IBM
This is the third time in less than 10 years that Fujifilm,
working with IBM scientists, have achieved such an accomplishment.
The team at IBM has focused on improving head technology to
produce stronger magnetic fields needed for improved tape capacity, speed and
reliability, while leveraging Fujifilm's advanced NANOCUBIC technology, looking
forward, these large capacity tapes will prove to be the most reliable and
affordable storage alternative, satisfying the requirements for big data and
To help reach this milestone, IBM researchers developed new
- enhanced write field head that enables the use of much
finer BaFe particles
- advanced servo control that allows head positioning with
nano-scale fidelity and enables a 27 fold increase in track density compared
- innovative signal-processing algorithms for the data
channel that enable reliable operation with an ultra-narrow 90nm wide GMR
