Two dimensional coding for a multiple-track, maximum-likelihood digital magnetic storage system
Paul Davey, T. Donnelly, D.J. Mapps · IEEE Transactions on Magnetics · 1994
Two dimensional run-length-limited (d, k/sub y/) modulation codes were recently introduced as a means of increasing storage capacity in multi-track recording systems. This paper furthers this coding technique by describing a reverse enumeration scheme based on the trellis description of the (d, k/sub y/) constraint for a channel employing extended class IV partial response signalling and maximum likelihood detection.>
