What does degaussing mean?
Hard disks and magnetic tapes use magnetic fields to store data on either the so called platters or on the tape. When degaussed, the magnetic fields are destroyed. Additionally, the degausser destroys all magnetic fields on the disks items, sectors and all data.
What does degaussing do to a hard drive?
A magnetic field of such power not only offers the guarantee of successful elimination of data from newer hard disks but also to safeguard the investment of the future with the use of disks that have a high recording density and coercivity factor.
Not all degaussers can delete data from hard drives and tapes permanently. You must bear in mind that a magnet opposes some resistance to demagnetization – magnetic coercivity. Coercivity is the intensity of the reversed magnetic field that must be applied to a material to cancel its magnetization. For a degausser to be effective, it is necessary that it is able to generate a magnetic field of at least equal to 1.5 times the coercivity of the support that needs to be deleted.
What follows is that the higher the power of the degausser, the greater its effectiveness and the possibility to use it on future technology hard disks and other magnetic media. The degaussing procedure lasts only a few seconds; place the device in the compartment and push a button to initiate the demagnetization. The media will not be reusable after this procedure.
What are the benefits of degaussing?
Degaussing hard drive is a complete, quick, easy and quiet process!
With a degausser, you keep complete control of your sensitive data at all times – no need to pass your data to third parties to be disposed of.
Degaussing hard drives is 100% effective, even on damaged hard drives.
Hard drive components can be fully recycled once degaussed.
Cost effective – degaussing offers one of the most cost-effective erasure solutions. Purchasing a degaussing machine is usually a one-time investment.
