LTO Ultrium 3 tape incorporates 704 recording tracks (as opposed to 384 tracks on LTO Ultrium 1 and 512 tracks 
on LTO Ultrium 2) on a 12.65mm-wide tape. To enable accurate data writing and reading from such narrow tracks, a 
pre-recorded servo signal is utilized. The uniform thickness of TDK’s LTO Utrium 3 tape formulation provides totally 
stable servo signal output, thus facilitating bit-accurate performance.

Because the LTO Ultrium 3 data cartridge incorporates a longer tape 
length than previous generations of LTO Ultrium media, the reel hub's 
drum is subjected to exceptionally heavy stress. A newly developed, 
highly rigid multi-strut construction allows the drum to maintain its 
circular precision.

Tape Technology

From Gigabyte to Terabyte capacity: 

Forging ahead with higher density 

recording for LTO Ultrium data cartridges.

Featuring 704 data tracks arrayed on a 12.65mm wide tape, high-reliability TDK LTO Ultrium 3 

media reads and writes data with absolute precision.

Cartridge Technology

High-precision tape mechanism featuring multi-strut reel hub provides optimal tape performance.

From its first generation featuring 100GB (200GB with 2:1 compression) capacity and 384 recording 
tracks, to the third generation with 400GB (800GB with 2:1 compression) capacity and 704 recording 
tracks, the LTO Ultrium format has realized considerable recording density increases. The LTO Ultrium 
roadmap includes a sixth generation with capacity further expanded to 3.2 Terabytes (6.4 Terabytes 
with 2:1 compression). TDK is engaged in ongoing research and development to ensure optimal 
performance for future generations of the LTO Ultrium format

Quality checks and instant production tracking facilitate reliability.

TDK data cartridges are produced in a meticulously controlled clean production environment. They undergo a series 
of exacting quality checks during production and shipment. TDK’s exclusive production tracking system further helps 
facilitate the high reliability of TDK LTO Ultrium data cartridges.

Ultimate tape reliability is achieved through close cooperation with drive manufacturers.

Because TDK specializes in recording media, the company develops its data cartridges for compatibility with all 
drive models. From the initial stages of development, TDK exchanges tape and cartridge design information with 
drive manufacturers to ensure the creation of recording media is optimized for the broadest range of hardware. 
In the case of the LTO Ultrium 3 data cartridge, its open exchange procedures enabled TDK to become the world’s 
first manufacturer to pass strict certification testing by the CVE (Compliance Verification Entity), the organization 
that certifies LTO standardization. 

Finer Super Finavinx metal particles will be packed in higher density.

The recording material is a key component in facilitating optimal media performance. In the case of magnetic tape, 
higher recording density mandates finer magnetic particles. Through uniform dispersion of the particles on the tape 
and high-density packing, stable output is obtained. TDK uses ultra-fine Super Finavinx metal magnetic particles 
specially designed for each respective LTO Ultrium format. The company is actively engaged in developing materials 
to be used in next-generation LTO Ultrium media, which will have even higher recording density.

Original ultra-thin dual-layer coating technology boosts precision.

To realize higher density, shorter wavelength recording, the magnetic layer’s thickness must be reduced. To achieve 
this, TDK has perfected its exclusive, ultra-thin dual layer coating technology. The technology provides an outstanding 
magnetic coating with extremely uniform thickness. The uniform thickness eliminates output fluctuations (spacing 
losses) that can be caused by gaps between the tape surface and the read head.

Use of Super Finavinx metal particles 
with even finer particle size.
Exclusive ultra-fine Super Finavinx 
metal particles deliver performance and 
reliability. Designed specially for LTO 
Ultrium 3 tape, TDK’s ultra-fine, next-
generation Super Finavinx metal magnetic 
particles are utilized. The particles 
feature an exclusive three-layer structure 
that achieves high output power and 
outstanding resistance to aging. Stable 
output characteristics are realized.

High precision ultra-thin dual-layer 
coating technology provides stable 
output characteristics. 
Created with unique dual-layer tape 
coating technology, TDK LTO Ultrium 3 
media features a base film that serves 
as the foundation for an ultra-smooth 
non-magnetic first layer and a magnetic 
top layer. Because the thickness of 
the magnetic top layer is uniform to the 
nano order, high reliability and stable 
output are realized. 

Ultra-smooth magnetic surface 
achieves high S/N ratio while ensuring 
low error rate characteristics. 
TDK’s ultra-fine Super Finavinx magnetic 
particle and thin film dual-layer coating 
technologies form a magnetic layer 
with outstandingly uniform thickness. 
The smoothness of the magnetic surface 
eliminates spacing losses. A high signal 
to noise ratio (S/N) is realized, promoting 
low error rate characteristics.

TAPE MADE WITH CONVENTIONAL TECHNOLOGY 

Multi-strut reel hub ensures 
drum’s circular precision.
It is important for the reel hub’s drum 
to maintain circular precision. TDK’s 
innovative molding technology limits 
the aberration from straightness of the 
drum surface to below one-fourth of the 
standard specifications. Featuring 
multiple supporting pillars that reinforce 
the wall of the drum, TDK’s multi-strut 
construction suppresses tape shaking 
to ensure stable head contact.

Hard metallic friction plate provides 
outstanding abrasion resistance 
and ensures stable rotation.
The locking pads, which supports the 
rapidly rotating reel, incorporates a 
specially treated hard metal friction 
plate that boasts minimal resistance 
with the contact areas of the brake lock. 
This ensures high rotational precision 
and contributes to a stable tape run.

Ultra-precise LPA mechanism 
features high clamping strength. 
The LPA (leader pin assembly), which 
serves as the drive’s access point, 
delivers unrivaled precision, with 
aberration less than one-fifth that of 
the standard specifications. What’s more, 
the perpendicularity aberration between 
the leader pin and leader tape is less 
than one-half that of standard 
specifications. High clamping strength is 
maintained to realize stable performance 
and withstand the rigors of repeated 
loading and unloading.
