As you may well know, it is the birthday of Dennis Gabor. We reported to you this morning that Google is celebrating this in the way of a Doodle on its homepage. We discussed the fact that he was the inventor of Holography, which the physicist released to the world in 1947.
We have a lot to thank Dennis Gabor for, even the future launch of the Holographic Versatile Disc (HVD) — which many see as the successor to the Blu-ray optical disc. The reason for this is that this next-gen holographic storage can hold 6 terabytes, that’s several times more that the Blu-ray.
This is all made possible because the collinear holography uses two green lasers to point into a single beam, this can then read the encoded data from the holographic layer that sits at the top of the HVD. A red laser is also used, but this will read servoinformation from an aluminum layer that is at the bottom of that same disc.
This certainly shows how fast technology is moving, but this latest advancement would not have been possible if not for Dennis Gabor. It seems that the inventor will live on forever, even after death.
