And now, some present-day holographic storage news, and the catalyst for our look to the future of ultra high-capacity data storage. General Electric this week unveiled a micro-holographic disc with the capability to store 500GB of data. Aimed at archivists, but ultimately at us lowly consumers.
They're the same size as today's DVDs, and similar to the holographic storage media we've already discussed, store data in three dimensions rather than as pits in a disc.
We expect this will be a pre-recorded medium to begin with, loaded with the next generation of video formats. Darren Waters on the BBC News technology blog wonders, "A single GE disc could be used to package up a library of high-definition movies, but is there pent-up consumer demand for such an offering?"
We can't help think Mr Waters may have missed one crucial point: such a pre-recorded disc could be used to store tomorrow's video content: 3D TV, or images with much higher resolutions than Blu-ray's 1080p. It's not going to be used to peddle our measly current-generation videos. The very thought!
