Reel and Cassette Format Magnetic Tapes

Clear magnetic tapes by either re-recording (overwriting) or degaussing. Clearing a magnetic tape by re-recording (overwriting) may be impractical for most applications since the process occupies the tape transport for excessive time periods.

Clearing by Overwriting
Overwriting should be performed on a system similar to the one that originally recorded the data. For example, overwrite previously recorded classified or sensitive VHS format video signals on a comparable VHS format recorder. All portions of the magnetic tape should be overwritten one time with known nonsensitive signals.
