A degausser is a device that erases data in hard drives, tapes, and floppy disks. A degausser alters the magnetic domains of these storage devices to disable the recovery and readability of data.
Etymology of Degausser?
Degausser came from the unit of magnetism called “gauss” which was named after German mathematician and physicist Johann Carl Friedrich Gauss. The term “degaussing” was also used by Commander Charles F. Goodeve to refer to methods that counter German magnetic naval mines during World War II.
How Does a Degausser Work?
A degausser operates by putting any magnetic medium through a strong magnetic field to change the particle polarity, entirely erasing any traces of previously recorded information. The degausser’s design makes it possible for the generated magnetic field to be made available to the media when it is moved through it. This can be done by either holding the media in your hands and moving it manually through the field, having it automatically transported by a belt transporter, or rotating on a motorized spindle.
Why Use a Degausser?
Magnetic media cannot be entirely erased by simple overwriting. Only a degausser can totally wipe data and guarantee that private information is securely destroyed.
These are the uses of a degausser.
- Disposes of sensitive media efficiently, safely, and internally
- Ensures that any sensitive information has been completely wiped out
- Significant operating cost savings
- Enhancement of output quality
- Compliance with the standards of the NSA and CESG for the sanitization of classified information
