Abstract
We consider a new constraint for improved timing recovery in partial response digital magnetic recording. The one-pairs constraint is an upper bound on the maximum number of symbols between pairs of ones in a coded sequence and can be considered as an alternative to the widely-used (0,G/I) constraint. We derive the capacity of this constraint, compute the power spectral density for maxentropic one-pairs constrained codes and give rate 16/17 and 24/25 block codes for this constraint
