National
Security Approved
The
best security in CD/DVD format control.
The
PER-1250 provides the ultimate remedy for data control for
Writable, Re-writable and CD and DVD media, and assures Department
of Defense destructions requirements are met.
PER-1250
is simple to use and offers quiet operation to cleanly and
completely declassify a wide variety of optical media.
This
patented device, employing "micro indentation" reliably
penetrates the data surface of target media, destroying the focal
plan and any readable data, and that allows for standard disposal of
the media.
A
large, secured, 4 cubic food "tote" stores hundreds of
declassified CD's and DVD's.

ATTENTION WHEN DEGAUSSING:
Please note the following suggestions when using
a Degausser:
Watches:
Remove your wristwatch when using the Degausser.
Direct exposure to the magnetic field may damage some watches.
Magnetic
Strip Cards:
Do not place your wallet or purse containing
credit or phone cards directly on or above the conveyor belt. Magnetic
strip cards are very easy to erase. However, having a wallet in
your back pants pocket while using the Degausser will not erase
the cards.
Tape storage:
Store videotapes you do not intend to
erase approximately four feet from the Degausser. This will eliminate
the opportunity for the operator to accidentally run “good” tapes
through the Degausser.
Placement
of Tapes:
When erasing tapes, place them on the left edge
of the belt (as you face the machine). In order they may travel
the full length of the conveyor belt for quality erasure.
Pacemakers:
Do not operate the Degausser if you have a pacemaker.
ABOUT DEGAUSSING MAGNETIC MEDIA
An alternating current (AC) bulk eraser (Degausser)
is used for complete erasure of data and other signals on magnetic
media. Degaussing is a process where magnetic media is exposed
to a powerful, alternating magnetic field. Degaussing removes
any previously written data, leaving the media in a magnetically
randomized (blank) state.
The Degausser must subject the media
to an alternating magnetic field of sufficient intensity to saturate
the media. Then the Degausser by slowly withdrawing or reducing
the field leaves the magnetic media in a magnetically neutral state.
To erase
recorded data, it is necessary for the strength of the degaussing
field to be greater in value than the coercivity of the magnetic
media. Simply stated, coercivity is the magnetic field strength,
rated in oersteds (Oe), required to change the magnetic orientation
of the magnetic material. Check with knowledgeable dealers or Degausser
manufacturers to identify Degausser models that meet your requirements.
Examples of typical coercivities for computer magnetic tapes and
disks are shown in table I.
Data is typically not lost until its level has
been decreased 65% to 75% (or more) below its original saturation
recording signal level, dependent upon the drive system.
A complete erasure level, for most users,
is considered to be 60 dB below the original signal level – this
of course depends on user requirements. A 60 dB signal decrease
equates to reducing the signal to one tenth of one percent of its
original value.
Magnetic media products that have factory pre-recorded
magnetic servo patterns should not be degaussed. Degaussing would
erase the factory written magnetic servo signals and leave the media
unusable. For all other magnetic media (without magnetic servo signals),
after proper degaussing, the quality of subsequent data recording
should be unchanged or even improved.
It is very important
to understand and follow the Degaussers operating instructions.
This is especially important for manual units where the operator
controls the media’s movement through the degaussing field. For
higher coercivity media, four passes are often recommended – two
passes, with a 90 degree rotation for the second pass, and then
repeat the process with the media turned upside-down. Of course,
these and other important operating considerations will vary with
the type, power and construction of the individual Degausser models.

* NOTE 1: DO NOT DEGAUSS
This product has factory prerecorded magnetic servo tracks. The media will be unusable, if the servo tracks are bulk erased
(degaussed). Products that use factory prerecorded magnetic servo signals should not be degaussed unless destruction of the recording media is desired.
