Two-dimensional magnetic recording (TDMR) by shingled magnetic recording (SMR) exploits two-dimensional signal processing using the waveforms reproduced by array head from intended and adjacent tracks. However, array head has the issue on the degradation of bit error rate (BER) performance due to head skew. In this report, we evaluate the BER performance of SMR R/W channel with head skew under the specification of 4 Tbit/inch2 by low-density parity-check (LCPD) coding and iterative decoding system with the equalizer using the two-dimensional finite impulse response (TD-FIR) filter for multiple read-back waveforms. |
