  Abstract

Bit-patterned media recording is the future magnetic data storage system that can achieve improved areal density. However, the spacing between islands must be reduced to increase areal density. This reduction increases the effects of inter-symbol interference and inter-track interference. According to lithography approach, the bit-patterned media layout can be designed as a regular array or a staggered array. Staggered array layout can reduce the effects of inter-track interference, resulting in improved performance. It is necessary to determine an appropriate detection scheme for improving the performance of staggered BPMR systems. In this paper, we propose a soft output Viterbi algorithm with weighted average in staggered bit patterned media recording.
