Two-track codes for magnetic recording channels
A reduction in the track-width in disc-recording systems results in a desirable increase in areal density, but also in the undesirable appearance of inter-track interference (ITI) and loss in signal-to-noise ratio (SNR), in addition to intersymbol-interference (ISI). One way the effects of ITI may be alleviated is through the use of multiple-head systems simultaneously writing and reading a number of adjacent tracks. We investigate the performance of two-track detectors, and design codes that combat two-dimensional interference patterns, ISI in the axial dimension and ITI in the radial dimension.
