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.
The DoD has approved overwriting and degaussing for purging data, although the effectiveness of overwriting cannot be guaranteed without examining each application. If overwriting is to be used in a specific application, software developers must design the software such that the software continues to write to all addressable locations on the media, in spite of intermediate errors.
