DVDs that store 10,000 films

Basically, the disc is clear, and information is stored on different layers within the disc which would greatly increase its storage capacity relative to a traditional disc with a single metal layer.

Well your sorta right, a CD only has one layer, I believe a DVD has 10 layers.

And your clear disk has an infinite (almost) amount of 'layers' in the sense if 2 or more lasers can intersect a point (an atom possibly?) within the disk it can write one bit of data there.

Ok, regarding these "Dimensions" they are not referring to Spacial, or Temporal dimensions.

Allow me to extrapolate:

A current hard drive or CD uses 2 dimensions to store information.

X: Distance from center
Y: Angle around circle (0deg - 360deg)

A double layered DVD uses 3 dimensions.

X: Distance from center
Y: Angle around circle (0deg - 360deg)
Z: Layer (1 or 2)


This new technology would use 4 dimensions.

X: Distance from center
Y: Angle around circle (0 deg - 360deg)
Z: Color of light to embed*
T: Polarization of light (0deg - 360deg)**

Footnotes:

* - IT is possible to create transparent mediums that respond differently to different wavelengths of light, such as a mirror that reflects blue, but absorbs red. So, instead of a laser creating "Pits" in the surface of the disc (essentially a binary 1 (pit) and 0 (flat)), you would place a certain color reflector that would return a different value based upon its spectrum, this would change the Pits in the Disc from a Binary storage, to More than binary (Octal, Hexadecimal, etc) that is limited only by the wavelength (size) of the beam, and the sensitivity of the scanner (How many colors it could differentiate)

** - By creating reflectors (mirror) with a polarizing surface (en.wikipedia.org...) the light sent in as a omni-directional polarity (Scattered and random) would only be reflected at the polarity that was stored in the "Bit"

This would enable you to create another level of data storage:

For a storage of binary you would have a polarity of:
1: 90 deg
0: 0 deg

with a more sensitive detector...

... it should be possible to store extremely massive ammounts of information on a single "Bit"

Very interesting! However, let's look at Moore's law.

en.wikipedia.org...

It seems we are surpassing this? I'm not claiming to be a specialist in this field, all I am doing is asking people to help me understand how this technology has become available to all of us!

Sorry, i know this post is quite old but Moores law will stop being a law once we reach quantum computing which is only about 25 years away i think,that means everything is instant.Down with the transistors! some people say longer but i think 25 years...maybe even 20 if we see a big breakthrough.Which we kinda already have as scientists have already tested a quantum computer...a very simple one with only a few atoms but stilla breakthrough.

There's work on a cheap disk and player that is suppose to come out in under a year by an actual inventor unless sony bought him out but his deal was he was going to compete directly with sony by making the disk and player cheaper than a blue-ray or so he use to say the last I heard it holds 2terabytes and was being referred to as the holographicdisc.

I just checked looks like he was bought out because they are now projecting 15,000 for the player when the original inventor was talking about 100 a pllayer and a buck a disk too bad really lol shoot. Looks like they modified the name a bit also.

holographic data storage anyone?

Holographic data storage is a potential replacement technology in the area of high-capacity data storage currently dominated by magnetic and conventional optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium. Holographic data storage overcomes this limitation by recording information throughout the volume of the medium and is capable of recording multiple images in the same area utilizing light at different angles

That is awesome.
I done a bit of reading. It is 10x cheaper to manufacture the Blu Ray per GB and Nintendo is going to be using this tech in the next Gen Consoles.

blog.tmcnet.com...

Holographic Multi-media devices and peripherals have been around for the past two decades at least.
The elite in the Military have it all at their disposal. The only time we will ever see it is when they can downgrade it enough and then sell it off to the private industry for a profit and a sole monopoly.

And technology itself should be commonly owned collectively. I treat all patents as crimes against humanity.

Harddrives are different and are actually following a different development...

A known future development is considering the use of solid state RAM-based HDD's! For those who are well versed in modern computers, will realize, HDD's aren't keeping up with computer hardware in terms of computer speed!!

Say if current HDD's have no problems with speed, installation of software, should only take a few seconds or no time at all. You don't have to wait for games to load, copying huge files will be near instant speed or few seconds... In addition, you can use some spare space in a RAM-based HDD to enhance performance of your computer, much like adding extra RAM sticks!

I have seen the solid state hard drives on the market for about a year for desktop PC's, they have probably been around longer.
I read they can boot your PC up in under 5 secs.
Last time i looked it was about $1000 for 80GB, i would rather a few min for my pc to boot up my 1TB HDD that cost me $120.
But once they come down in price they will be well worth it.

Wow, that's incredible. Very amazing.
I can't wait till these hit the shelves!

Hey folks, I had read part of the article a while back and then I stumbled onto here and saw the same thing super DVDs. I have posted the research article that describes how this is possible:

rapidshare.com...

If you folks want more cool stuff just wiki holographic versatile discs. The thing I dont like is that the people who make the discs try to milk us out of all the money by slowly releasing low technology things and making the money off of it first before releasing something better.

Look at the exponential factor in data storage

3.5 in floppy to cd = factor of increase 500
cd to dvd = factor of increase 7
dvd to blu-ray = factor of increase about 7

There should have been a factor of increase of 500 from cd to new storage medium:

700mb x 500 = 350 GB

They are slowly trying to milk us of our money. I will not be surprised if we have to wait 20 years for this.

holographic storage has been around for a while, but not in the private sector, mainly in large corporate and Military applications. I read on the InPhase site that a system is $18,000. But With Nintendo bringing this to their nex-gen console hopefully in the next few years it will start popping up in lounge rooms.
I agree with what your saying about them milking us, read my post the (2nd last) on the first page.

I was into this subject a few years back and remembered something I found
50 TB Protein coated DVD discs

www.engadget.com...

I will dig up some research articles from the past related to storage mediums....when I have the time and see the ultimate limits. I think for now that 50TB protein discs and this new ultra-DVD are the top competitors...it leaves HVD in the dust at a mere 6TB of storage capacity
