What is a Degausser?

It is a machine used to eliminate data stored on computer and laptop hard drives, floppy disks and magnetic tape, by randomly changing the alignment of magnetic domains on the medium.

Data is stored on magnetic media by making very small areas called magnetic domains change their magnetic alignment to be in the direction of an applied magnetic field. Degaussing magnetic media leaves the domains in random patterns with no preference to orientation, thereby rendering previous data unrecoverable. A degausser is therefore used to completely erase all audio, video and data signals from magnetic storage media.

This process is effective in a range of industries including video, audio, computer, broadcast and data security.

Benefits of Using a Degausser

Assurance that all sensitive data has been erased permanently

Disposes classified media quickly, safely and in-house

Improvement in the quality of output

Sizeable savings in operating costs

Meets the NSA and CESG requirements for sanitisation of classified information

Simply overwriting magnetic media does not completely erase data. Only a degausser can remove data 100% and ensure that confidential data is securely and completely erased.

How does a Degausser work?

It works by passing any magnetic media through a powerful magnet field to rearrange the polarity of the particles, thus completely removing any resemblance of previously recorded data. Although this process of course is simple in theory, in practice, the vast variation of media formats and magnetic densities makes the correct process quite difficult to achieve. The degausser is constructed in such a way as to enable the generated magnetic field to be available to the media when it is transported through it, which can be by physically holding the media and moving it through the field by hand, having it automatically conveyed by a belt transporter or rotated on a motorized spindle.

More About Magnetic Media

The term magnetic media covers a vast range of material from audio/video tapes and cassettes to computer diskettes and reels, supplied in a wide choice of sizes and complexities. All of them however, perform in the same basic way yet have significantly differing characteristics in performance and in operation that will require differing erasure processes.
