| Holographic discs enter the storage war |
| Tuesday, November 29, 2005 at 13:52 by Andy Holliday |
300GB Holographic discs will go on sale towards the end of 2006, analysts predict.
Hitachi and InPhase Technologies are jointly developing the technology - which could even be developed to store a whopping 1.6TB of data.
The holographic storage systems use laser-light interference to store data into a light sensitive crystal material. They can also offer read/write speeds of up to 120 Mbits / sec.
Holographic storage works by splitting light from a single laser beam into two: the signal beam to carry the data and the reference beam. The hologram is formed where these two beams intersect causing a chemical reaction in the recording medium. By varying the reference beam angle, wavelength, or media position many different holograms can be recorded in the same volume of material.
Could this be the breakthrough that the industry needs to improve performance, capacity and cost? It certainly sounds like it. Could Blu-ray and HD-DVD be doomed before they've taken off? Only time will tell...

| Just when the government is making us buy HD TV equipment it is becoming extinct! Ain't that a kick in the pants? |
|
|
| HD for television means Hi Definition and has nothing to do with High Density or Hard Drive. ph00l |
|
|
| I believe HVD will instead of DVD and VCD!!!! |
|
|
| i think this technology will be great for out future |

| At first I thought this sounded like a really great idea, but my enthusiasm is waning. For one thing, do things like HD movies need 300GB - 1.6 TB of space? No I think not. HD-DVD and Blu-Ray offer the necessary amount of space, but without the huge price you will inevitably shell out for the HVD and HVD player. Plus, this technology is only writeable once at the current time. Sure, someday it will go RW, but every RW CD and DVD is much less reliable than it's one-time counterpart, so it would be expected that writing multiple times to an HVD would also experience this same thing. The only practicle use I can see for this type of media is as a backup drive, but I don't know of anyone who wants to be paying $120 dollars daily for a backup disc, and $15,000 for the drive.
I think that, atleast until there's a more practicle alternative, I will be sticking to HDDs and HD-DVD/Blu-Ray (whichever wins the format war). |
