| Outline of Final Research Achievements |
I evaluate the bit error rate (BER) performance of two-dimensional magnetic recording (TDMR) R/W channel with head skew under a specification of 4 T bit pre square inch employing low-density parity check coding and iterative decoding system using a two-dimensional finite-impulse response filter with the array head by computer simulation. The results show that our system can achieve the reliable BER performances by appropriately setting the reader scanning positions at the larger head skew angle.
