The article analyses performance of in-track iterative decoding over a Two track recording system with a one-head and a two-head detector. A two-track system is modeled as a partial response of in-track inter symbol interference (ISI) channel with linear symmetrical inter track interference (ITI). It is presented the bit error rate performance of in-track low-density parity-check codes, used with various ideal partial response equalization targets (Dicode, PR4, EPR4, E2PR4 and ME2PR4), over two-track magnetic recording system.
