ABSTRACT:

Digital magnetic recording/playback systems usually require both
runlength-limited (RLL) coding and error correction coding (ECC), and these
two steps have typically been performed independently, although various
methods of combining them have recently appeared. The recent development of
two-dimensional modulation codes, which meet runlength constraints using
several parallel recording tracks, has significantly increased the capacity
of such channels. In this paper, we apply single-track coding ideas to these
two-dimensional constraints, and exploit the increased capacity to achieve
good error-correcting quality at the same rate as common
non-error-correcting one-dimensional codes.
