    摘要: A write head degaussing circuit (40) and methodology configured to end the degaussing signal (66) a selectable percentage short of the tapered degaussing waveform, starting the degaussing of the write head current Iw at a percentage less than Iw, removing any overshoot of the degaussing signal, and any combination of the above.
