Definition Edit

Erasure is

[a] process by which a signal recorded on magnetic media is removed. Erasure is accomplished in two ways: (1) by alternating current erasure, by which the information is destroyed by applying an alternating high and low magnetic field to the media; or (2) by direct current erasure, by which the media are saturated by applying a unidirectional magnetic field.[1]
