• Bit patterned media (BPM)
• burst error
• low-density parity check (LDPC) code
• product code

Bit patterned media aims at high density recording of more than 10 Tb per square inch, but a burst error mostly occurred by media defects, and data write failure can be a serious problem. However, if the burst errors are compensated by erasure decoding, the performance of low-density parity check (LDPC) code, which is a strong candidate for the error correcting code for storage systems, can be improved. In this paper, we propose an iterative LDPC-LDPC product code and show that it performs better than a simple LDPC-LDPC product code when there are only random errors and both random and burst errors.
