Abstract

In this paper, a burst detection scheme using a parity check matrix of LDPC code is described for the perpendicular magnetic recording using a bit-pattered medium. It is assumed that the burst-like bit-flipping occurs due to missing the write synchronization. The phenomenon cannot be detected as a signal decay and significantly degrades the performance of the LDPC coding and iterative decoding system. Therefore, a good alternative detector is required in order to keep the performance. The LDPC coding and iterative decoding system is evaluated by the computer simulation in a perpendicular magnetic recording channel using a bit-patterned medium with the burst-like bit-flipping. It is clarified that the LDPC coding and iterative decoding system with a burst detector has the resistance to a burst-like bit-flipping of 200 bits.
