Abstract
We propose a system for magnetic recording, using a low density parity chec k (LDPC) code as the error-correcting-code, in conjunction with a rate 16/1 7 quasi-maximum-transition-run channel code and a modified E(2)PR4-equalize d channel. Iterative decoding between the partial response channel and the LDPC code is performed. Simulations show that this system can achieve a 5.9 dB gain over uncoded EPR4 The algorithms used to design this LDPC code are also discussed.
