Extremely high areal density utilized submicron trackwidth recording was proposed. To overcome the difficulty in tracking servo to follow the narrow track, multi-track parallel recoding is effective with a wider track read haed. A new encoding/decoding scheme introducing multi-level partial response is investigated. It is demonstrated by an experiment that recorded information on two tracks can be descriminated even with a single widetrack read head by means of this scheme.
