ABSTRACT:
A device for degaussing magnetic transducers used with magnetic stripe cards includes a degaussing unit that drives a magnetic transducer with an electrical pulse, or a gradually increasing drive frequency, to eliminate the residual magnetism of the transducer. Logic circuitry controls the device to degauss with little or no additional equipment and avoids damage to the recordings, as on low-coercivity magnetic stripe cards.
