Abstract :
Partial response maximum likelihood (PRML, (S.X. Wang, 1999)) magnetic channels offer optimum bit error rate (BER) performances inside certain ranges of recording densities and SNR values. In order to extend these performances outside those ranges, supplementary processing of detected sequences is required or channel coding techniques that limit the effect of intersymbol interference (ISI) by separating magnetic transitions. In many cases though, this leads to loss of disk space due to the redundancy inherent to channel codes. This redundancy can be significantly reduced if classic run length limited - RLL (d, k) codes are replaced with maximum transition run - MTR-RLL codes
