Real-Time Recording Results for a Trellis-Coded Partial Response (TCPR) System

Abstract

This paper describes the results of an experimental performance comparison between a Trellis-Coded Partial Response (TCPR) system and a Partial Response Maximum Likelihood (PRML) channel, using magneto-resistive (MR) recording heads and metal film disks. Measured data confirms that the TCPR method provides substantial performance advantage in terms of on track error rate, offtrack capability, and areal density. © 1993 IEEE
