  abstract: The goal to increase the amount of information that can be
  abstract: stored per disk unit area in digital recording systems
  abstract: continues to be important, together with the tendency to make
  abstract: recording systems physically smaller. An obvious way to
  abstract: increase information density in existing systems is to
  abstract: increase the number of bits per track and the number of
  abstract: tracks per unit area. Several detection schemes proposed for
  abstract: multi-track, multi-head, digital recording systems as well as
  abstract: theoretical studies about achievable radial information
  abstract: densities in these systems suggest that, if construction of
  abstract: head-arrays simultaneously scanning multiple tracks becomes
  abstract: possible, areal storage density can be greatly increased by
  abstract: means of track narrowing. The main advantage of using
  abstract: multiple-heads is their capability to partly recover the loss
  abstract: in performance due to inter-track-interference (ITI), which
  abstract: is a prominent noise source in narrowtrack systems. Since
  abstract: track-narrowing also results in a decrease in signal-to-noise
  abstract: ratio (SNR), multi-dimensional modulation codes for improving
  abstract: noise immunity are needed to compensate for this. We show
  abstract: that codes designed for improving noise immunity in single-
  abstract: track, single-head systems provide the same coding gain when
  abstract: used in multitrack, multi-head systems when ITI satisfies
  abstract: certain conditions. These conditions are only sufficient but
  abstract: they do not impose significant requirements for most common
  abstract: ITI models where only adjacent tracks interfere. For the
  abstract: special case of the two-track, twohead, dicode channel, we
  abstract: design a class of two-dimensional constrained codes capable
  abstract: of recovering the performance loss incurred by both presence
  abstract: of ITI and decrease in SNR for large interference levels. The
  abstract: construct finite-state encoders with sliding block decoders
  abstract: and reduced-complexity Viterbi detectors for several high
  abstract: rate codes in this class. The codes discussed here are
  abstract: derived for a special model of interference that exists
  abstract: between tracks even if there is no servo positioning error.
  abstract: However, the codes are expected to be applicable to systems
  abstract: with known and unknown servo positioning errors as well. We
  abstract: show that these multi-track, multi-head, coded systems
  abstract: potentially provide a substantial areal density increase even
  abstract: in cases of high ITI.
