: Because of residual traces of magnetism. These can be used to recreate the
: old data. The same happesn when you tape a piece of music and overwite it
: with a new piece of music. Very softly the old music may be heard (unless
: you tape heavy metal the second time ;-).
:
: The NSA has come up with a method to whipe magnetic media clean and consist
: of overwriting the content with 7 different sets of 'data' before the tape
: is considered to be erased (safely).
