Disclosed is an apparatus for destroying electronic memory media by use of a bi-directional degaussing device. The degaussing device utilizes an SCR gate controller to cause bi-directional polarity from a charged capacitor into a sealed chamber containing the magnetic media. The chamber has a movable steel plate cover and floor that encloses the chamber containing magnetic media during the degaussing stage. The cover and floor cause a reflective chamber that focuses and directs the flux level to the magnetic media. The gate controller allows the use of the same capacitor bank to power a coil in two different directions to obtain effective degaussing without multiple coils or directional capacitors. |
