Verity Systems Security Products has its roots in the defense and security industry. We design, manufacture, and sell the most extensive range of degaussers and data destroyers on the market, suitable for all types of magnetic media, making us the market leader in data destruction.

Our engineers have over 30 years’ experience in designing and manufacturing degaussers, previously under the Verity brand. Applications range from security erasure of hard drives and backup tapes, the erasing of broadcast audio and video tapes for recycling purposes, to the physical destruction of hard disk and solid state drives

Customers worldwide are supported by our global distributor network to ensure that the high standard of customer service we demand is achieved.

Degaussing: An Introduction

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.

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 sanitization 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.

Operation of Degaussers

The operation of degaussers will vary depending on the type and quality of media and the speed and degree of erasure required. When erasing tapes, either the cassette must move through the magnetic field or you must move a magnetic field over the cassette. In each case, the consistency of the motion, the strength of the field and the distribution of that field over the entire media are what determine the quality of the erasure.

Most professionals and engineers agree that a conveyor transport degausser, which allows the user to place the magnetic media on a small belt, which in turn passes the media through or over the degaussing coils at a constant speed, assures the most uniform process. Custom-designed degaussers can assist with the specialist needs of bulk operators with belt feed conveyors; collection hoppers are available to deal with tapes, disks and reels, all helping in making the operation effective & efficient.

Effective degaussing is very much a performance factor of the machine and generally passing the media through the field twice does not improve the effectiveness. If however the media is rotated by 90 degrees, some improvement can be achieved. Verity Systems Security Products have developed an eraser employing "state of the art" technology that uses a rotating coil technique. The media passes on a variable speed conveyor belt through a field, generated by two powerful coils, which are rotating, one above the media, the other beneath it.

With the ever-increasing demand to fit more & more data on smaller media, there is now a requirement that can be more important than absolute erasure. That is consistency of erasure.

It is widely understood that data at a high packing density stored on magnetic media is easier to erase than lower density data. The data signal-to-noise ratios, bit-to-bit phase relationships, and amplitude variations all become more critical and require more sophisticated electronics to ensure valid error-free data recovery. Variations of magnetic flux, remaining from a poor erasure cycle, will make data recovery more difficult and will result in increasing errors.

Points to Consider When Choosing a Degausser

  1. Type of media used: What formats do you need to be degaussed? Different degaussers can handle different types of media.
  2. Volume of media: How much media do you need to degauss and in what sort of timeframe?
  3. Density of media: Magnetic media varies in its density. You will need a degausser with enough power to completely erase data on your media.
  4. Type of Operation: Manual or Automatic. Do you have enough time to erase tapes manually or would you prefer an automated system?
  5. Proposed location of degausser: How much room do you have for a degausser?
