Abstract

This paper presents two coding approaches of concatenated single parity codes together with their implementation and performance evaluation. The first approach uses two concatenated single parity bit codes along the track direction separated by a Dithered relative prime (DRP) interleaver. While the second approach uses the two single parity bit codes in both along and across track directions without interleaving. The results obtained for situations of high inter-symbol interference (ISI) and inter-track interference (ITI) show a better performance with the former approach as against the latter applied in a two dimensional magnetic recording media (TDMR)
