Abstract

The signal processing requirements are described for a single magnetic recording channel with a very high transfer rate (117 Mb/s). On the record side it is necessary to compensate for the relatively slow rise-time of the head fringing field. On the playback side the use of Class IV partial response improves the effective signal-to-noise ratio. A Viterbi detector operates on the redundancy inherent in the ternary partial response samples to provide further processing gain.
