Abstract
A new method for evaluating the power spectral density of multitrack constrained sequences is demonstrated for multitrack (O,G/I) constraints. (O,G/I) constrained sequences are used in magnetic recording systems that employ partial response maximum likelihood (PRML) signalling. Using the proposed approach, the number of states in a directed graph representing the given (O,G/I) constraint is reduced remarkably so that the power spectral density can be easily calculated
