Enhanced data storage and retrieval devices and systems and methods for utilizing the same

Abstract From the Canadian patent

The invention relates generally to store information on magnetic or optical storage media by using one or more novel approaches alone or in combination. These novel approaches are capable of using at least one code which may comprise more than two values (figure 4d 43). A first series of approaches , for the storage of information applies generally to optical recording and reproducing system (figures 7-10, optical media 66) while a second series of , approaches applies generally to electric or magnetic recording and reproducing systems (figure 1-2, magnetic medium 1) Each series of approaches is capable , of storing information data in one or more codes (figure 4d 42a, 42b, 42c, 42d) …
