DOI: 10.1109/access.2022.3182801
Abstract: We consider a prospective island distribution of bit-patterned media recording (BPMR) that consists of a hexagonal array called a staggered BPMR. Although the staggered BPMR can reduce two-dimensional interference, including intersymbol interference from the downtrack… read more here.

DOI: 10.3390/app10155295
Abstract: A bit-patterned media recording (BPMR) system is a type of ultrahigh-capacity magnetic storage system that can extend to an areal density of 1 terabit per square inch or higher. However, because the space between islands… read more here.
