Abstract: Provided herein is an apparatus including a rectangular array of rectangular protrusions in a first region corresponding to a data region; and a hexagonal array of circular protrusions in a second region corresponding to a servo region, wherein a first global protrusion density for the first region is greater than a second global protrusion density for the second region. Also provided herein is a method including forming a first template; forming a second template; and cross-imprinting the first template and the second template to form a third template corresponding to the foregoing apparatus.
