摘要：

Bit-patterned media recording (BPMR) is a promising approach to push back the onset of the superparamagnetic limit faced by conventional granular media recording (CGMR). Previous work in this area has characterized the position jitter and size jitter from fabricated media at recording densities ranging from 0.6 Tera dots per square inch (Tdpsi) to 2.9 Tdpsi, and the characterizations were used to predict expected densities from the BPMR system. In this work, we investigate the impact of a few critical parameters towards the final performance of the BPMR system in terms of the written-in-error (WIE) rate.
