Shingled magnetic recording (SMR) is employed to realize higher recording densities in hard disk drive (HDD). In this report, we investigate the dependence of decoding reliability on recording condition by classifying the log-likelihood ratio (LLR) at a posteriori probability (APP) decoder output, according to the recording patterns. The results show that the decoding reliability for ``010'' is lowest on the decoding target track. Furthermore, the decoding reliability for ``011'' and ``011'' strongly depend on the recording condition of the decoding target bit and the recording pattern on the adjacent tracks. |
