Optimized for High
Capacity
The Ultrium tape format is the implementation of the LTO (Linear Tape-Open)
Ultrium Technology that is optimized for high capacity and performance with
exceptional reliability in either a stand-alone or an automated environment. It
uses a single reel cartridge to maximize capacity. Ideally suited for backup,
restore, and archive applications, the Ultrium tape format establishes a new
benchmark for large volume backup and archive. Ultrium technology products will
meet the needs of the enterprise through single-server user on a roadmap, or
migration path, that extends well into the next decade.

High Capacity |
|
|
Ultrium
technology allows for 800GB capacity native, 1.6TB compressed (2:1) in a
single compact cartridge. The cartridge is smaller than existing
single-reel tape cartridges.
|
|
High Data Rate |
|
|
Ultrium
technology provides for data transfer rates of up to 240 MB/second (2:1
compression) for Generation 4 products.
|
|
LTO-CM
(Cartridge Memory) |
|
|
Enhances functionality by
providing a redundant file log as well as user-defined information. An
external reader allows immediate access to that information without
having to insert the cartridge into a drive.

|
|
Ultrium
format products take advantage of LTO Technology's proven error
correction and data compression techniques.
|
|
Flexibility |
|
|
By specifying only those
features needed for interchange of tape cartridges, the Ultrium format
retains flexibility. This flexibility allows for a substantial amount of
implementation freedom with respect to performance characteristics, form
factor, reliability, controllers, and interfaces - while tape cartridges
remain interchangeable among Ultrium format tape drives.
|
|
Consistent Servo |
|
|
The servo format is expected
to remain consistent throughout the life of the product line. This major
benefit enables manufacturers to leverage investments.
|
|
Multi-Sourcing |
|
|
Multiple sources for media and
drives reduce production bottlenecks and also ensures investment
protection for OEMs and end users alike.
|
|
Compliance Testing |
|
|
By an independent organization
promotes compliance to the specification. This shortens qualification
cycles and simplifies future product planning for OEMs. |

Approximate cartridge
dimensions: 4.1 x 4.0 x 0.8 in. (105 x 102 x 21 mm) (smaller than most
existing single-reel tape cartridges).
The single-hub design allows for the cartridge to be optimally packed with
media. High capacity is further enhanced by the use of an LTO Technology
data compression algorithm with two control modes to maximize compression
efficiency.
LTO-CM is a noncontacting passive RF interface embedded in the cartridge
which allows remote reading of the contents of the built-in 4KB (32 Kbits)
of non-volatile memory. Calibration information, manufacturers' data, and
information about initialization may be retrieved without having to insert
the tape cartridge into a drive.
Dedicated dual servo: The servo bands are pre-written on the tape during the
tape cartridge manufacture process. If one servo element becomes defective,
or if a portion of the servo code on the tape becomes corrupt, the head will
continue to track as a result of the second "redundant" servo system.
Longitudinal position words encoded within the servo frames allow efficient
access to absolute locations down the length of the tape.
Data integrity features include two levels of error correction that can
provide recovery from longitudinal media scratches. Read-While-Write (RWW)
capability allows real-time verification of written data.

The expandability in the design of the Ultrium product line results from
combining and leveraging enabling technologies to produce a technologically
solid migration path. This Flagship (8-channel version) Migration Path
describes improvements of the premium products in the line from generation
to generation.
