Abstract :
This paper is focused on the design of partial response equalized channels and maximum-likelihood sequence detection for high density magnetic recording systems. Methods for designing linearly equalized partial response channels are presented and applied to a Lorentzian model for the magnetic recording channel. Reduced-state maximum-likelihood sequence detection methods are employed for the partial response equalized channels and the error rate performances of the detectors are evaluated
