CDS-1500 DEGAUSSER

The CDS-1500 Professional Degausser speeds up the degaussing process of both high and low density 3 ½” and 5 ¼” diskettes, 3480 data cartridges and more. Complete erasure is accomplished as the conveyor belt transports the media through strong horizontal and vertical degaussing fields produced by the degaussing coil. For added convenience, the conveyor belt speed can easily be adjusted up to 60 feet per minute. At this rate, the CDS-1500 will erase more than 200 diskettes per minute. For more efficiency, add the optional diskette feeder and down-stacker. Each is available for either 3.5” or 5.25” diskettes.

            Degaussing Coil:

For long-lasting performance, the degaussing coils are vacuum dipped and baked. The vacuum process draws the air out of the coil allowing the potting compound to coat each winding of the coil. The coil is then baked “rock hard” to eliminate vibrations that could eventually lead to shorts in the windings of the coil. In addition, two thermal detection units have been wound into each coil to ensure that the operating temperature is safely maintained. When in operation, the coils are cooled by fans which are automatically turned on and off by the signals being sent from the thermal detection units.

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 degausser’s 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.
