摘要：

We present a semi-analytical approach for the analysis of synchronization in bit patterned media (BPM) recording. The analysis is based on full numerical micromagnetic calculations of the reversal surfaces of separate BPM element. These reversal surfaces are used to define writing window zones for correct recording in BPM element arrays. The simulations show that staged media lead to improved performance and larger writing window zones (WWZs). The presented model and results are important for estimating BPM designs in terms of density, bit-error rates (BERs), and performance.
