Holographic Storage a Reality in 2006? 214
vitaly.friedman writes "What do you do when you're getting close to the limits of 2-dimensional optical technology? Well, how many dimensions do we have to work with?" From the Ars Technica article: "How much greater data density? In the Hitachi Maxell device, a single disc about 1 cm larger in diameter than a CD will buy you 300GB. By way of contrast, HD-DVD currently offers a maximum of 30GB on a 2-layer disc, and Blu-ray tops out at 50GB. Although upgrades are in the works that promise to increase the capacity of both of those formats, even the most pie-in-the-sky predictions fall short of what is planned for merely the first commercial generation of holographic storage. Future plans for that medium include boosting the capacity to 800GB in two years, and 1.6TB per disc by 2010."

Maybe not even 1CM.. 2-3CM would be just fine. An important question is why the hell does all of our media have to be huge? Something the size of a flash card or slightly larger would be MUCH better. I'd take a 2.5CM disc with 30GB storage over a 8-9CM disk with 400GB storage any day.
Imagine your whole 300+ movie collection weighing less than 5 lbs and taking a cubic foot of shelf space including the case!

I want a cube. I want a cube about 1cm^3 in size. If that's too thick, a 2x1x0.5cm sliver is OK. Preferably translucent moss green, but other colors are of course also acceptable as long as they've appeared for futuristic storage in at least one reputable sci-fi movie.
To be slightly serious, there's non-aesthetic reasons for this as well. With optical storage it's much faster to move the beam around than the media, and with rotating media your seek and read times alike are limited by the rotation speed.
But mostly I just want a translucent green block because it's cool. Bonus points if there's a small LED inside making it glow.

For example, my main concern with this new storage is that it will hold a ton, but will still only have the couple year shelf-life that DVD-Rs and CD-Rs have.
As storage space increases but shelf-life lags behind, it becomes increasingly riskier to actually use that full amount of space because you're basically putting more of your chickens in one basket.
Does anybody know of any current developments that are working to solve this issue? Is having a home server the best way to reliably store all those old CD-Rs?

Maybe this IBM Millipede [ibm.com] thing would float your boat. It uses nanotechnology to push indentations into a plastic card.
I think they're working on the translucent green part now.
Don't make them too small, dammit. (Score:4, Interesting)
I have a belt bag for my Nintendo DS. I keep six GBA games on the side pocket. GBA games are small enough, yet not too small, easy enough to handle. But currently, I'm keeping one Nintendo DS game in the console itself and keeping the others in my bag in the retail packages. DS games are much smaller than GBA games. I keep worried that I might lose them. I'm trying to come up with a decent, safe enough solution. (Let's see if I can find my old wallet that had all those pockets, that ought to do the trick...) I always get the same sort of worries with memory cards, SIM cards, etc...
The point is, the smaller the storage media comes, the easier it is to lose.
I'm all for 1 cm disks, as long as they come with a caddy that is half the size of a 3.5" floppy.

1 GB on a fingernail. (Score:4, Interesting)
I got one of those new "chocolate" cell phones. Cool. It takes a Micro-SD memory card, so I went to my local computer superstore to get one.
A one GB micro-SD memory card cost me $74.00. I'd never seen one before, and when I opened the package I was afraid the wind would blow it away. It's litterally smaller than my little fingernail and about as thick as a potato chip. A 7x7 grid of these cards would be 49 GB, and easily fit within the bounds of an ancient 1.44 MB floppy disk case. Hell, you could fit three or four layers of 7x7 grids of these things in that case.
Ok, so $3626 might be a bit pricey for a movie disk, but the technology is there. It's just a matter of price. Remember, all the features in this $149 cell phone would have cost well over $Ten Grand thirty years ago and would have required a suitcase full of hardware too.
I predict than in 20 years or less, we'll have terrabytes on disks the size of a quarter.
