Abstract
Bit Pattern Media Recording (BPMR) is the modern HDD recording technique which can overcome the constraint of conventional technique by offering tremendous areal density. However, narrow track of BPMR can cause noise generating from inter-track interference (ITI) and In. inter-symbol interference (ISI). One traditional technique used to improve BER of the system is the introducing of error control coding. In this paper, we investigate concatenate code applied to BPMR. We proposed inner code with low-density parity-check (LDPC) and Reed-Solomon (RS) codes as outer code. The obtained simulation results confirmed to us that the concatenated coding scheme yielded better performance compared with the single LDPC code deployment.
