The Challenges for Tape
How small can magnetic particles be without losing their
magnetic power?
How thin of a magnetic layer can be coated uniformly on
tape?
How well are these smaller particles uniformly dispersed
within new polymer compounds?

What is so great about Barium
Ferrite?
25
To begin,
let’s look at the fundamentals of
magnetic recording…

26. FUJIFILM Confidential
Single Bit Cell These are “magnetic particles”
＋ bit cell ＋ bit cell ＋ bit cell－ bit cell－ bit cell
26
Surface of Magnetic tape
Data tape consists of tiny microscopic “magnetic particles” uniformly
dispersed and coated on the surface of tape, then small cells so called
“bit cell” are written onto it.
Each cell is magnetized as either positive or negative and multiple
combinations become data (just as digital data is made up of 1s and
0s).
Bit Cell & Magnetic Particle

27. FUJIFILM Confidential

New Particle to Support Future Tapes
The biggest difference of LTO6 from the past
generations is that this time Fujifilm elected to
use Barium Ferrite magnetic particles instead of
using the current metal particles.
Again, this is Fujifilm’s unique technology.

3 Major Benefits of Barium Ferrite

understand the 4 features of Barium Ferrite.

Example: Compare high resolution picture and low resolution picture.
Smaller the particle, larger the data in one bit cell. More
data in a cell results in less noise and clearer signal.

35. FUJIFILM Confidential
Disadvantages of MP
• MP’s magnetic property depend on it’s aspect ratio. As
the size gets smaller magnetic property becomes lower
(performance as a magnetic particle becomes poor).
• MP is horizontally magnetized whereas Barium Ferrite is
vertically magnetized.
2. Perpendicularly Magnetized
35
Advantages of Barium Ferrite
• Barium Ferrite’s magnetic property does not
depend on it’s shape.
• Barium Ferrite is perpendicularly magnetized.

36. FUJIFILM Confidential 36
2. Perpendicularly Magnetized
－ Bit Cell ＋ Bit Cell － Bit Cell＋ Bit Cell
－ Bit Cell ＋ Bit Cell － Bit Cell＋ Bit Cell
Because MPs are horizontally magnetized, the particles
tend to cancel (demagnetize) each other → Output Loss.
Since Barium Ferrite is perpendicularly magnetized, above
phenomenon does not occur.

37. FUJIFILM Confidential
3. High Magnetic Property
37
Barium Ferrite magnetic
particles has a higher
magnetic property
compared to metal
particles.
High magnetic property leads to
less output loss.

The gap between Output and Noise shows the performance of
the tape. We call this Signal to Noise Ratio (SNR).

Barium Ferrite is compared to tape using MP.

High Capacity “Bit Size and Capacity”
Barium Ferrite enables production of
tapes with much smaller areal density
resulting in tapes with much higher
capacity.
This is possible because Barium
Ferrite tape has great performance
even when bit cells become small.

Fujifilm’s Barium Ferrite magnetic tape particles established the world’s
highest areal density of 29.5 billion bits per square inch.

Oxidized Material
Long Archival Life

51. FUJIFILM Confidential
MP is mainly made of iron (Fe) therefore it will oxidize after time
and it’s magnetic property will deteriorate. In order to slow that
down, outer layer of MP is intentionally oxidized from the beginning.
3. Barium Ferrite is an Oxide (=stable material)
51
Barium Ferrite is mainly made of an oxide,
therefore it does not lose it’s magnetic
property due to oxidization.

Since Barium Ferrite is an oxide
it does not deteriorate due to

-Tape storage is proved to be the ideal solution for high
capacity, high reliability, efficiency and low cost archiving.
-Technology to support tape’s largest benefit “high capacity”
has been continuously improving. Now with the Barium
Ferrite, tape proved it’s potential to support another 10 year
roadmap and in 2011, StorageTek’s T10000 (5TB) and
IBM’s JC media for TS1140, the two first tape cartridges
using Barium Ferrite were introduced.
-Fujifilm is determined to continuously contribute to future
development of tape to meet increasing demand of data
recovery and data archive requirements.
