Parallel Detection Based on a Generalized Partial Response Target for Staggered Bit-Patterned Media Recording Systems

We consider a prospective island distribution of bit-patterned media recording (BPMR) that consists hexagonal array called staggered BPMR. Although the BPMR can reduce two-dimensional interference, including intersymbol interference from downtrack direction and intertrack cross-track direction, structure is unsuitable for detection schemes regular In BPMR, islands along neighboring tracks are skewed by half period on main track. Consequently, an track distorted four closest two To detect data, based generalized partial response target, we divided into three parts applied one-dimensional detectors. Then, to estimate original signal, averaged outputs The simulation results demonstrate proposed model improves performance compared with those described in previous studies.
