ABSTRACT:
A method for providing transverse magnetic bias proximate to a pole tip to speed up the switching time of the pole-tip during the writing operation is disclosed. The transverse field disposed proximate the pole-tip helps the conventional driving field in rotating the magnetization through the first 90-degrees, especially at small angle where the effective anisotropy-field is strongest in opposing the conventional driving field. By offsetting the magnetization from its easy-axis, the transverse field also increases the torque that the collinear driving field would have on the magnetization.
