This paper outlines the basic features and applications of partial-response and maximum likelihood sequence estimation signal processing in digital magnetic storage. The paper also introduces a practical examle of PRML channel combined both these technologies. Especially, PR(1,0,-1) decoding way using Viterbi detector is reviewed in a circuit structure, a timing recovery way and the performance. Moreover, several advanced signal processing technologies applicable to the magnetic storage are examined for future developments.
