    ABSTRACT: Conventional method for media defect recovery in a low-density parity-check (LDPC) coded magnetic recording channel is erasure decoding. In erasure decoding, read back signal in media defect region is erased and not used in channel detection or iterative decoding. In this paper, a new method based on full-response reequalization, in which media defect corrupted signal is first reequalized to full response then partially used in iterative decoding, is proposed. Simulation results show significant performance improvement over conventional erasure decoding in both non-precoded and preceded channels.
