  Abstract

The layout of bit islands in bit-patterned media recording (BPMR) can be arranged in various structures such as regular- and staggered-array bit patterns according to the lithography approach. The main difference between the regular- and staggered-array bit patterns is the effect of inter-track interference. In this paper, we propose an iterative concatenated coding scheme using the three-path soft output Viterbi algorithm for a staggered BPMR system. The proposed concatenated coding scheme, which consists of inner and outer low-density parity check (LDPC) codes, can help improve the performance of BPMR because of the iteration between the inner and outer codes using extrinsic information.
