Abstract
An optimized six-dimensional storage system has been investigated theoretically. The system uses multiple beams to create overlapped micro gratings as each storage cell. The cell capacity depends exponentially on the beam wavelength number. With two-photon absorption writing, coherence tomography reading and superresolving beam focusing, this system has extra-large capacity of >1 Pbyte per DVD sized disk (potential ~60 Pbytes per disk), extra-fast reading speed of >117 Gbits/s with high signal-to-noise ratio of >66 dB, large cell sizes (~0.3μm × 6μm) which greatly reduce data addressing difficulties and a standard drive like structure compatible with the CD and DVD disks.
