Mass production starts next year

NTT CLAIMS to have made a high capacity memory device using a multi-layered waveguide structure based on thin film lithography.
The device is the size of a postage stamp and made from plastic material, with the prototype having 1GB capacity.

It has also made a prototype drive to read data from what it calls the Info MICA media and is set to commercialise both these ideas, with mass production to start next year.

The media is recyclable, has high memory density, copying of the media is difficult, mass production is relatively inexpensive, while the drive’s power consumption is very small, claimed NTT.

Here comes the optical revolution.
 
Yep. I suspect thsi is where storage is headed in the long term. This is merely the opening salvo.

Really...I would've thought that nano-hard-drives and Fluorescent media disks (FMDs)...something not so sensitive to magnetics. The hologram drives sound interesting though...you've caught my eye :) Thanks Prof!!
 
Nanos and FMD have durability failings to overcome yet. Holos are old tech, with high durability. Just look at your credit card.

Holos are optical, Bish. No magnetics

My skills in bad sentencing are unequaled sometimes. What I'd meant to say was that FMD's were not-magnetically succepteable while nano-HDs were.

Prof: FMD's don't have issues with longevity...they're effectivly as long-lived (or longer) than CDs or DVDs....as for holograms...it depends on the material it's placed on (in). If we're talking glass or rigid plastics, it's fairly shattereable, non?
 
CD-R only have a 2 year lifespan. CD-RW are shorter. CD and DVD average less than 10 years. Holos average 200 years, due to density and array effect (lost bits can be recovered by checking adjacent bits.)

What about write-rewrite?

Here's the specs from some of the FMD info that I have:

ClearCard reader drive
Fluorescent multilayer technology is not limited to circular spinning discs. Constellation 3D has already demonstrated a 10 layer and 20 layer ClearCard (FMC), a storage device that can be produced in any form factor, including postage stamp sized SmartMedia or credit card sized. Right now, storage in a card format is used in a variety of applications: digital cameras, portable PCMCIA storage for laptops, E-books, smart cards for holding personal data for use in casinos, airports, etc. Besides the huge storage amount, the best thing about Constellation 3D's ClearCard is the price. Although they haven't yet set a price, it will be much cheaper than current Compact Flash and MicroDrive card-type storage devices. To put it in perspective, the cost of manufacturing a 10GB ClearCard is less than $10.

FMD ClearCard™ WORM (Write Once Read Many) Card​
This is a development of the ClearCard ROM, which enables the user to select information to be stored. Writing and​
reading are performed using a powerful semiconductor pulse laser. The planned initial production model is a credit​
card-sized ClearCard-WORM with up to 10 layers and up to 1GB capacity.​
Future Disks & Cards​
The planned second and third generation cards and disks will have capacities up to and exceeding 1 Terabyte (1,000
Gigabytes). RAM versions of disk and card are also planned. ClearCard Technology​
 
Knew I'd find it eventually.

Research has shown that systems using fluorescent material resist corruption much longer than naked systems. And researchers have recently posited devices containing as many as 100 layers separated by fluorescent coatings -- shattering earlier forecasts of feasible storage capacities

best estimates... 4-8 times the lifespan of a DVD - that's 40-80 years. Anything that you need to store beyond that would be so outdated that it wouldn't be the effort.

There are a few exceptions. Books, movies etc...art..but I would expect that if/when better storage came along, that these would change media as well. For instance, you won't find microfiche being used very often anymore...or audio-tapes.
 
Blue laser was supposed to rip the CD market a new hole, with 4 times the data compression. 10 years ago. It never made it to market.


BTW, when you post stuff from another site, espescially images, please put links, so we don't get sued. Thx.
 
I follow a lot of this stuff with great interest. I can never figure out what's going to make it and what isn't. BTW, I have a Betamax vcr in my attic.
 
Beta was far superior to VHS. But proprietary systems never work in a public market. IBM never recovered from the MCA conspiracy. And though they had MCA as far back as 286, it wasn't bettered until Pentium class machines with Win9x/PCI came out.

FWIW, I think MCA is still better...but, as you mentioned, the superior product isn't always the best product. Just think...If the Apple Newton had sold better, and worked as advertised, most of us would not know what a Palm Pilot is... ;)

As PMd...this info exists as a PDF from the Pub.Relations of the company. Their web-site is down, 'cause they jsut got 'acquired'. No links to post...though I suppose that I can try to find similar sites and post those links.

VHS is still better than DVD. More space for sound tracks, better colour delineation, especially in the blacks.

I can't for the life of me find any Dolby 6.1 VHS tapes, and in my strictly subjective opinion, DVD pictures are much more crisp than VHS (so were Beta).:shrug: Re the FMD, I've been following it some, it seems really promising but years away. I think holographic storage will beat it to the market by quite a bit. That's not to say that holographic storage won't get replaced.

I think analog tape can only store stereo (2ch). Digital tape might be able to do separate channels, but I bet they are pretty much limited to TV production facilities due to high cost.
