    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 ontrack error rate, offtrack capability, and areal density.
