Minimum distance analysis of multihead multitrack recording channels

In English We perform a minimum distance analysis of a class of two-dimensional
inter-symbol interference~(ISI) channels applicable to multihead
multitrack magnetic recording systems. Exact minimum distance for a
wide class of ISI responses is derived. The fundamental analytical
technique that we apply is to transform the channel into an
equivalent minimum phase channel. When compared with prior related
work of Soljanin and Georghiades, the results derived in this paper
are more conclusive and improve upon theirs.
