InPhase Technologies Promises Holographic Drive in May 194
Anonymous Coward writes "After 8 years of effort, InPhase Technologies is shipping the world's first holographic disk drive next month. They showed it at this week's NAB. With a 300GB 5.25" disk cartridge and a 50-year media life, the Tapestry 300r is aimed at the video and film archive market. They've been promising this thing for so long I'd given up hope that they'd ever ship it!"

Presumably, however, holographic storage has so much dang storage available that it's not a problem to give some of it up to have enough redundancy to survive typical wear and tear. (And all optical media gets wear and tear just from being spun up and down in non-cleanroom environments.)
And if you're worried about the longevity of CDs and DVDs, scratches aren't really what you're worried about anyway. Most scratches are on the clear plastic and can be repaired. However, some discs were manufactured with chemicals that oxidizes the layers, some with defects in the seal, etc. So your typical "stamped" disc will last decades if free of defect, but less than a decade if it has one-- and there's almost no way of knowing ahead of time. I don't know what substrate the holographic image is being stored on, but we'll have to see if it's completely free of degradation over decades. I certainly wouldn't want to immediately dump important data into this format and throw away the originals yet.
So for now it just remains an expensive unproven alternative... we'll have to see where it goes, though.
Target Market? (Score:2, Interesting)
Which gets us to InPhase's target market: archiving. That's why they were showing at NAB.
I don't get it. No matter how valuable your content, why would you pay $18,000 for a burner and $180 for for a 300GB disc? Just for the price of the media, you can mirror your data across three different brand-new hard disks. Surely the odds of 3 hard disks failing at the same time are lower than that of an untested, brand-new technology with no redundancy?
Maybe I'm too thick, but why would anyone buy this at this price? (Other than the coolness/my dick is bigger than yours factor, of course.)

- It may indeed last 50 years, but will the equipment it's to be connected to? I've got the first 100MB drive to hit the market. It has lots of stuff on it I want to retrieve. It's a good thing I've kept the 18 year old Apple IIgs it's inside of operating.
Better implemented on solid state holographic storage, but still possible on disk, is the reverse processing of image to beams. (There's a SciAm article from 1995 or so on holographic storage, particularly solid state, that covers this).
Store lots of images on the disk. Illuminate it with a hologram of a target image. Out of each image comes copies of the original reference beams, at a strength proportional to the similarity of the stored image to the target image. Nearly instantaneous, simultaneous retrieval with correlation score built into the signal strength. Lost is the different angles that'd be had in a solid state device, so scanning the disk for reading all the beams and finding those of interest might take a bit longer. The entire US government fingerprint files could fit on one disk and the whole thing searched in seconds, as is often seen on TV. Using it for movie storage makes marketing sense, especially with the initial price tag of $18,000 and disks being $180. But leaving it at that would be a damn shame.

This is not quite correct. Sure, if you zap them with a large enough static charge it will burn out the chips - but this is more likely to apply to the interface chips rather than the flash that carries data. Flash is also susceptible to radiation. Otherwise it is pretty robust.
Holographic storage however, likely relies on some sort of photo-sensitive dye or phase change material - which will have big problems if you leave it inside a car during a hot summer day.

Think about those early 10 megabyte hard drives. Take that form factor and blow it up over the same length of time and you get some crazy-huge numbers. A third dimension to play with? That's like going from DC to AC in terms of complexity and possibility. Interestingly enough, the establishment resisted AC as well. I half suspect that the math simply demanded more brain power than the old school engineers were willing or able to invest.
I remember the day when a roommate took the indoor cat out to the roof. The cat saw the sky for the first time and wet itself, flattened right to the ground and was basically reduced to a form of catatonia. After living in a one-floor apartment, (two-dimensional), being presented with a whole lot of up and down created a great deal of irritation.

It would make sense if you used this storage to not put it into cold-storage, but put it into some kind of server-room that provides ro access to the data in a secure and safe fashion.
This would allow studios to work with their raw data without risking the loss or damage of the actual physical medium.
Also, you should of course store additional backups offsite.
For the price it's not bad, no hard drive is guaranteed 50 years. I'm lucky to get 5 years nowadays, I have 6 dead hd's over 80gb sitting next to me.
Reminds me of the Pinnacle Apex drive... (Score:3, Interesting)
If the technology in this stuff pans out and can be developed economically and scale well over time (MO didn't), I think it has some real opportunities to take off in certain sectors. It's not for everyone, but neither are rackmounted RAIDs, iSCSI and tape loaders.
For naysayers: do any of you think that this company WANTS to release a boat anchor device like it seems to be going by their pictures? If what the company says is true, and this is not vaporware, the physical size of the drive may be a worthwhile trade-off in terms of capacity and reliability. As technology is developed, processes shrink, things get cheaper, and storage capacity gets bigger. I remember old MO drives being big, and as some pointed, out, a single CD-R costing $40.
I'm not going to buy this thing, but I'll certainly be watching its development in the marketplace. It's interesting to watch, just like I did the Apex back in the day.

Supprisisngly it doesnt make much difference to your numbers over a relatively short period like 3 1/2 years:
today $100 for about 26 Gig (using your starting point of $30 for 8 GB)
1 year from now - 68 Gig
2 years from now - 175 Gig
3 year - 450 Gig
4 years - 1.2 Tera
I have also studied hard drives in the same way and they will "only" be about a $50 for a Terabyte in 4 years if trends of the last 5 years continue.
