Described are optical recording media for recording data in voxels, the optical recording media including a plurality of data recording regions for recording the voxels, the data recording regions separated by buffer regions having optical properties such that illumination from a reader that enters one of the data recording regions remains preferentially confined in said one of the data recording regions until being scattered by interaction with one or more of the voxels. Also described are methods for reading the described optical recording media, which include separating the light received from illuminating the voxels based on wavelength, polarization, or other optical properties.
An optical recording medium for recording data in voxels, the optical recording medium comprising a plurality of data recording regions for recording the voxels, the data recording regions separated by buffer regions having optical properties such that illumination from a reader that enters one of the data recording regions remains preferentially confined in said one of the data recording regions until being scattered by interaction with one or more of the voxels, wherein the data recording regions and the buffer regions are arranged in layers through a thickness of the optical recording medium, wherein the buffer regions have a higher refractive index than the data recording regions, and wherein the buffer regions, and wherein each of the buffer regions has a refractive index profile that varies through the buffer region thickness from a first surface to an opposing second surface to have a lower refractive index near the first and second surfaces and to have a higher refractive index in a center portion between the first and second surfaces.
An optical recording medium for recording data in voxels, the optical recording medium comprising a plurality of data recording regions for recording the voxels, the data recording regions separated by buffer regions having optical properties such that illumination from a reader that enters one of the data recording regions remains preferentially confined in said one of the data recording regions until being scattered by interaction with one or more of the voxels, wherein each buffer region comprises three layers, the layers arranged such that a higher index of refraction layer is sandwiched by two lower index of refraction layers, each of the layers of the buffer region having a higher index of refraction than that of the data recording regions.
A method of reading voxels recorded in an optical recording medium comprising a plurality of data recording regions for recording the voxels, the data recording regions separated by buffer regions having optical properties such that illumination from a reader that enters one of the data recording regions remains preferentially confined in said one of the data recording regions until being scattered by interaction with one or more of the voxels, the method comprising:
