ABSTRACT:
A write pole for vertical magnetic recording is described. It includes a trapezoidal prism of high magnetic moment material, having inwardly sloping sidewalls. Its parallel surfaces are between about 0.1 and 0.3 microns apart and the sidewalls slope in the range of 15.5 to 60 degrees relative to vertical.
