What is Degaussing. Degaussing is simply the act of erasing data from magnetic media. Sometimes it is referred to as sanitization.. It works by subjecting magnetic media to a strong magnetic field that removes data from data bearing surfaces. The magnetic field can be created either by powerful magnets or an electromagnetic discharge.
Degaussing takes its meaning from Johann Gauss (1777-1855) a mathematician who studied and worked on electro-magnetic fields. It is used today to describe the process of erasing magnetic media i.e., removing from that media, remnants of previously recorded signals.
