Degaussing definition

Degaussing is the process of decreasing or eliminating a remnant magnetic field. Degaussing is used to destroy data held on magnetic storage such as computer and laptop hard drives, discs, cassettes, etc. Degaussing is a guaranteed form of erasing data on a hard drive, which is a standard method of data destruction, ensuring that your information is no longer retrievable.
