Bell Labs spinoff InPhase Technologies is developing a new data storage system using 3D holograms, due out in a few years. It will allow a CD-ROM size disc to hold 400 gigabytes, enough to store 100 full-length feature films.

The technology will feature an ultra-high-speed data transfer rate, allowing for downloading an entire digitized movie in 30 seconds.

The U.S Defense Department’s National Imagery and Mapping Agency is a sponsor.
