Media durability is measured in tape passes. A
DLTtape™ IV tape cartridge can be run through a
drive unit 1,000,000 times without wearing out!
However, tape passes should not be confused with
tape uses or mounts. A DLT™ drive lays down data
in a series of parallel tracks that run the length of
the tape. This continues, back and forth
(serpentine), until the tape is fully written or read.
As a result, it takes multiple passes to write or read
the full capacity (full tape access) of a DLTtape.
The four-channel DLT 8000 drive makes 52
passes to access a full tape. Assuming full tape
accesses for each use, dividing 1,000,000 by 52
passes-per-use equals 19,230 uses. Therefore,
under this condition the DLTtape™ IV lifetime on a
DLT 8000 drive would be 19,230 uses. The two-
channel DLT 4000 drive requires 64 passes for a
full tape access. Subsequently, the million pass
lifetime on a DLT 4000 drive would require 15,625
full tape accesses. Accordingly, a lifetime of at
least 15,625 uses is the worst-case scenario for
DLTtape™ IV.
In high duty-cycle tape applications, such as HSM,
Virtual Tape, Near-online, Primary Storage and/or
Temporary Output, the uses do not usually require
the maximum number of passes. Consequently, in
high duty-cycle applications, a lifetime much
greater than 15,625 uses can be anticipated!
On the other hand, backups that require one or
more full tapes would use the maximum passes for
each use. However, backup is a low duty-cycle
application. Even with a short seven-day retention,
it would take 300 years to use a tape 15,625 times
for backup. Even daily use on an application
requiring the maximum passes for full capacity
access would require over 40 years to reach
1,000,000 passes.

Data Cartridge Durability
Fujifilm DLTtape
™ IV is the answer to the high-capacity storage and archiving needs of mid-
range systems, network servers and high-end workstations. Native capacity of up to 40GB on
a single tape combined with sustained transfer speeds of up to 6MB/second provide the
performance essential to data-intensive applications. 
Unsurpassed durability. Low error rates.  Long archival life.
These attributes are guaranteed when you buy Fujifilm
DLTtape™ IV.
DLTtape™ IV features Fujifilm’s exclusive ATOMM (Advanced super
Thin layer & high-Output Metal Media) technology - a unique dual
coating system that provides greater storage capabilities than ever
before.  DLTtape™ IV provides a storage capacity ranging from 20
GB to 40 GB (native capacity) or from 40 GB to 80 GB (2:1
Compression).
Fujifilm’s design ensures read compatibility with future generations
of DLT.  It also takes advantage of shorter wave length recording
schemes.  Solid and liquid lubricants reduce tape and head wear.
The chemical design resists retention of airborne particles that could
also affect read/write head performance.  Fujifilm’s cartridge shells
are shock resistant and provide additional corrosive protection.  A
tape reel locking mechanism protects the media by preventing tape
slack.
ATOMM (Advanced super Thin layer & high-Output Metal Media)
technology makes revolutionary tape capacity and reliability possible
for the DLTtape™ IV system by simultaneously coating the tape
base film with an ultra-thin magnetic layer and a non-magnetic lower
layer. ATOMM dual coating technology features a high density ultra-
thin upper layer of magnetic material with a highly smooth, glossy
finish. This is made possible by the extremely hard, smooth surface
created during simultaneous coating of the minute spherical
particles in the "titan-fine" lower layer; these particles are roughly
one-sixth the size of metal magnetic particles. Lubricants are
optimised in both upper and lower layers.
