ABSTRACT:
An apparatus, system, and method are disclosed for writing magnetically encoded data. A servo module positions a write head relative to a first land such that a first edge of the write head is positioned substantially over a first land edge of the first land. The write head has a radial width greater than the sum of a radial width of the first land and radial widths of interior and exterior grooves such that the write head is also positioned over at least a portion of a second adjacent land. The write head writes magnetically encoded data to the first land. The servo module further positions the write head relative to a second land such that the first edge of the write head is positioned substantially over a second land edge of the second land and the write head is not positioned over the first land.
