Abstract

Multi-level partial response channel is investigated for submicron-trackwidth multi-track recording based on high areal density perpendicular magnetic recording. The assumed single-pole head combination is a multi-write head of submicron-trackwidth and relatively wide single read-head. Encoding rules including zero-level magnetization for the partial response channel is proposed for the head and the channel combination. A simulation assumed ideal playback waveform and an experiments with actual heads show availability of the method.
