Yep.  The magnetic media retains a trace of everything that was recorded 
on it. If you have recorded over an old cassette tape, you may still be 
able to discern the original recording under the new recording.

Gutmann method might be excessive but any software that uses it shows a 
seriousness about security.  Plus I don't have to do all that writing. 
The computer does it for me.

Wipe looks like a good start.  Thanks for the tip.
