University of Arizona researchers have developed a material that can create rewritable holograms, which could bring 3D displays to the home or provide high-capacity computer memory.

A layer of the material can record a holographic image, erase it, and replace it with another in a few minutes. The researchers hope to refresh pictures at video frame rates of around 30 times a second.

Other experts are skeptical of the approach as applied to data storage because the new system would require high voltages near the data storage media.
