Abstract
The tolerance for burst error of interleaved low-density parity-check (LDPC) code is evaluated with the cross-interleaved Reed–Solomon code (CIRC) in the magnetic tape drive using a BaFe magnetic tape. We evaluate the interleaved LDPC coding and iterative decoding system with burst error detector (LDPC-BD) system by the required signal-to-noise ratio (SNR) to achieve “No errors” for the burst-like deterioration such as media defects to the CIRC with erasure error correction (CIRC-EC) system by computer simulation. The results clarify that the LDPC-BD system tolerates the longer burst errors than the CIRC-EC system and the LDPC-BD system achieves “No errors” with the 3.0–4.5 dB lower SNR than the CIRC-EC system.
