CDS-4400ED Degausser
Product Description:

Continuous Duty Drive & Tape Degausser

Today's magnetic recording formats allow for more data storage, better video resolution, less video noise and higher frequency recording. The problem is these super-high coercivity media formats - 2400 oersteds for tape and 3000 oersteds for hard drives - are increasing and are very difficult to erase.  Conventional tape erasers just can't do it.  The solution is the CDS-4400ED Eliminator!

The CDS-4400ED Eliminator erases metal particle tape to -80dB (like new) in 12 seconds or less. IT departments will be able to erase the data including all formats and control track information on DLT's allowing them to be re-used in other DLT drives.  Further, IT departments are increasing there data security by degaussing hard drives before disposing of or transferring hard drives out of a secured environment.

Please note:  Degaussing of hard drives erases all data, formatting and the factory installed magnetic servo tracks located on the hard disc platters.  Therefore, the hard drive will be unusable after degaussing.

Broadcasters, video professionals and data centers save money through erasing and reusing their metal tape. And they don't sacrifice program integrity because the CDS-4400ED Eliminator provides like new erasure quality.

The world's leading tape manufacturers recommend the CDS-4400ED Eliminator. This is because it features patented technology that eliminates excessive heating of aluminum hard drive casings, metal cassette parts and reels that can damage tape. And this is done without compromising erasure quality.

The CDS-4400ED Eliminator will erase all formats including: Hard Drives, One-inch Tape Reels, VHS, U-Matic, S-VHS, MII, D1, D2, D3, D5, 4MM, 8MM, DLT, LTO Ultrium I-IV, HI8, DAT, DIGITAL BETACAM SP, DVCAM, DVCPRO, DIGITAL-S, HDTV and MIRROR IMAGE.

The popular CDS-4400ED Eliminator digital tape degausser is incorporates electro-magnetic field (EMF) shielding. The specially designed shielding reduces radiated EMFs by more than fifty-percent. The simple to operate CDS-4400ED Eliminator is the first conveyor belt style bulk degausser to offer EMF shielding. Now bulk degausser users can greatly reduce their exposure to EMFs without compromising tape erasing quality or productivity. This is a welcomed development for many broadcasters and production facilities that have standardized on the CDS-4400ED Eliminator.

Please note the following suggestions when using a Degausser:



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.



Do not operate the Degausser if you have a pacemaker.




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.

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.
