Abstract
Storage density in an optical data storage media and system is increased many times the resolution limit by fully utilizing the much smaller detection limit by differentiating and isolating the active data sites in the media optically. The tracks are preordained and predisposed to a specific optical property and value that is different from that of its "n" nearest neighbors but is identical to its nth neighbor and to the optical properties of the reading and writing optical system.
