PR5ML Processing for Perpendicular Magnetic Recording

Abstract

-The partial response class 5 (PR5) signal processing for perpendicular magnetic recording with single layer media is discussed. Several benefits of the PR5 system to channel coding and Viterbi detection are shown: applicable to both the d=O code and the d=lcode, interleaving signal processing, and the four-state in the Viterbi decoder. Basic configurations of the timing recovery for the PR5 system is also shown.
