Can holographic optical storage displace Hard Disk Drives?
Chu and colleagues explore holographic data storage as a replacement for hard disk drives, introducing an energy optimization framework for Fe concentrations in iron-doped lithium niobate. Their approach results in a record-breaking performance in both read and density.
The finding that the diffraction efficiency is at the maximum at specific Fe 2+ concentration is consistent with previous studies 19, but the point at which \({A}_{s}/{\tau }_{r}\) starts to decrease varies with the recording geometry, crystal size and beam profiles.
