Is degaussing an acceptable method for secure data deletion for magnetic media such as hard disks, floppy disks and magnetic tapes ?
According to international/industry practices, degaussing is considered an acceptable technical solution for secure data deletion for magnetic media such as hard disks, floppy disks and magnetic tapes if properly employed. During the degaussing process, the magnetic flux of the media is reduced to virtually zero by applying a reversing magnetizing field. Properly applied, degaussing renders any previously stored data on the media unrecoverable by keyboard or laboratory attack.
