In this paper, a new burst detection method using the check matrix of low-density parity-check (LDPC) code is proposed. The burst detection for the bit flipping burst-like signal degradation which the conventional burst detection using a reproducing waveform, an equalizer output, an a posteriori probability (APP) decoder output and so on cannot detect is studied. The performance of the LDPC coding and iterative decoding system with the proposed burst detector is evaluated by computer simulation for a perpendicular magnetic recording channel with bit flipping burst-like signal degradation, and it is compared with that of the RS encoding and decoding system using the erasure correction. The results show that the LDPC coding and iterative decoding system with our burst detector shows the better performance and has the resistance to the bit flipping burst-like signal degradation of about 1500 bits.
