摘要:
An information storage apparatus uses an optical data element (nano-grating) with features that are smaller than the wavelength of light. The optical data element alters one or more properties of the light such as reflected amplitude, polarization, phase, wavelength, and spatial orientation to encode data in a massively multi-level format.
