Will these discs be able to be written on by regular DVD writers? If so then we can put four DVD-9's on one AOD! How awesome would that be...

No way, Euro. NO WAY.

They are vastly different formats.

But it says that it's physically compatible with current DVD format. Do you mean that regular DVD writers are not able to write to them but that these discs are playable in regular DVD players?

instead of getting peoples guesses on items like this. lets just wait and see. we will not know the answer till its released

The EE Times announcement doesn't give enough information. "Compatible with current DVD format" is a phrase you should take with a grain of salt. You may be able to play a present-day DVD on this system, but there's _no way_ a present day DVD burner is going to burn a dual-layered <A>dvanced <O>ptical <D>isc !!!

The compatible means downwards compatible -- i.e. discs are same size and AOD players (just like Blu-Ray players/recorders) can _play_ DVD-Video discs. Just like DVD players can play CDs, but your CD player can't play DVDs.

Great Googly-Moogly! It's 5:34 AM Nova Scotia time, and you caught my post.

(I gues great minds never get much sleep, eh dRD?) :)

(I know, I know), It's a dirty job, but someone's gotta do it.

Don't forget to occassionally reply to the 'ban-request-thread', even if you don't agree with a particular request. (Thankee).

No.. For starters AOD uses 405nm (violet) laser. AOD needs an AOD drive to read/record the discs. I do see how my post can be misleading -- I should have underlined the difference between physical compatibility and logical compatibility.

The physical similarities between AOD and DVD are: same lens aperture (0.60-0.65 for DVD, 0.65 for AOD), same protective layer thickness (0.6mm), and the same free working distance (1.0mm). The specs for BluRay are accordingly: 0.85, 0.1mm, and 0.05-0.10mm. AOD discs, like DVDs, are used without a cartridge. BluRay uses a cartridge.

US Patented UV/Blue Holographic nanoStorage
will hold > 4,000 Blu-Ray disks.

Holographic Storage technologies will
start displacing other optical storage
technologies so we can have one format,
one drive type, one interface.

Keep an eye out as this technology starts
to appear in the next few years.

What? I hate those things. Why does it need a cartridge?

Probably to keep the surface of the disc dust and finger print free. A big, greasy thumbprint is bad news at BluRay data density. I don't have a clue how AOD addresses read errors.

AOD likely uses some heavy Forward Error Correction similar to Satellite systems to protect against noise (dirt). It's hard to believe that even the current CD standard uses three levels of forward error correction. Not to sure for DVD's, but AOD would certainly need to use some severe FEC as from what I can see, one spec of dust could potentially cover the area of 1,000's of physically written bits and maybe over 1 million bits for a small fingerprint.

They will initially be in a case, and then be available without I presume. Just like DVD RAM.
