<p>A magnetic head (10) vertically records information on a disk (12). The head (10) has a single pole (16) having a pair of erase band segments (24) which extend from a center pole section (26). When the head is writing information, the erase band segments (24) create erase bands (34) at the outer edges of the track (30) by not fully magnetizing the disk and/or increasing the azimuth angle of the magnetized outer edges. The azimuth angle can be increased by constructing the erase band segments (24) to extend at an angle from the center pole section (26). The reduction in field strength in the outer track edges can be accomplished by making the erase band segments (24) thinner to cause a saturation of the outer magnetic field. The weaker, angled outer track portions (34) do not generate a significant magnetic field in a head located on an adjacent track.</p> |
