In this report, we evaluate the performance of the write-margin for the low-density parity-check (LDPC) coding and iterative decoding system in the bit-patterned media (BPM) R/W channel affected by the write-head field gradient, the media switching field distribution (SFD), the demagnetization field from adjacent islands and the island position. It is clarified that the LDPC coding and iterative decoding system in R/W channel using BPM under 2 Tbit/inch^2 has a write-margin of about 20%. |
