Owing to the magical properties of graphene, we’re not just talkingabout a Blu-ray or DVD disc that has had its recording layer replaced with graphene, either — we’re talking about holographic storage with absolutely monumental capacity, intrinsically high security, and apparently the ability to recover the data even when the discs are broken.[/QUOTE] Source: [URL="http://www.extremetech.com/extreme/167931-scientists-create-the-first-graphene-based-holographic-optical-disc"]http://www.extremetech.com/extreme/167931-scientists-create-the-first-graphene-based-holographic-optical-disc[/URL]
I'm over circles. Can these be triangles instead?

Now make hard drives or magical NAND chips with graphene. Optical storage is useless, unless it has magical read/write speeds.
What's the first thing Australian researchers would put on a holographic storage medium? [IMG]http://www.extremetech.com/wp-content/uploads/2013/10/graphene-oxide-reduction-polymer-process-diagram-640x254.jpg[/IMG] A kangaroo.
Stop coming up with more optical disks already god damn, try and make cheaper and more reliable flash storage
[QUOTE=Thunderbolt;42406200]Stop coming up with more optical disks already god damn, try and make cheaper and more reliable flash storage[/QUOTE] Thing is that apparently optical technology is the future, we've already made a DVD with a one petabyte storage. We're also developing fiber optic circuits to replace the electric ones.

And there's a difference between optical storage and fiber optic circuits - fiber optic is faster, optical discs are slow, fragile, loud, most of the time read-only, and drives are much more mechanically complex and prone to failure than SSDs.

There's limits to SSDs that the current mediums don't have.
Storage space is great, but if you've ever tried to move 8Gb of files to a drive with 3mb/s transfer speeds, then you'll know space isn't everything
What's the longetivity compared to MO?
I imagine data retrieval from a broken disk would also be costly and not worth it to your average consumer.
It would be nice if things like this don't just disappear from the news after a single article. It'd also be nice to see it being used...
[QUOTE=Banandana;42413674]It would be nice if things like this don't just disappear from the news after a single article. It'd also be nice to see it being used...[/QUOTE] To be honest I'd rather see discs disappear. As superior as this is to the shitty discs we have now, discs in general are awful
Think that's enough worrying about storage right now and now focus on researching how discs can be read/written to faster. If someone manages to write a whole disc, how many years will it take to read it all back? CDs are already painful enough if data's being directly accessed instead of streaming.

CDs are already painful enough if data's being directly accessed instead of streaming.[/QUOTE] Optical storage was never designed for direct read/write operations. Data was either buffered and written or buffered and streamed. The media itself was designed as a high capacity long life format. You're also assuming we will one day reach a time where single files are tens of gigabytes or terabytes in size. Access times will never surpass that of a mechanical hard disk due to their design and therefore should remain as a long-life archival medium which in the case of Magneto optical has not only shown to be far more rugged but outlast practically every other data storage medium in existance. Unless semiconductor costs pass below that for optical media we will never see its replacement.
I remember hearing somewhere that graphene has similar effects on the lungs to asbestos. Imagine if we discover that graphene is the solution to all our engineering problems, only to find out it'll kill all of us. I can seriously see graphene becoming the next asbestos.
Good, now we can fit GTAX on there.

optical disks are great for storage but are useless for practical applications in consumer electronics so please make bigger and cheaper solid state drives
[QUOTE=K1ngo64;42416298]Forget to put disc back in case, gets small scratch. 5 years of human history lost.[/QUOTE] There's these things called backups right
I think it's useless if the only advantage is to recover data [IMG]http://goo.gl/Ou1SsM[/IMG]

[QUOTE=a-k-t-w;42416510]There's these things called backups right[/QUOTE] How long does it take to backup 1 petabyte?
[QUOTE=Thunderbolt;42406200]Stop coming up with more optical disks already god damn, try and make cheaper and more reliable flash storage[/QUOTE] Just because this news isn't what you want, doesn't mean nobody else is working on that. There's more than one scientist in the world.

Also, over 20 years as an adopted standard goes against your "useless for practical applications" statement.

[QUOTE=butre;42425172]the internet has made optical media as a distribution platform obsolete and you know it[/QUOTE] That's a very closed minded way of thinking about this. Optical media still has applications in the world, tons of them. They are great for backups (a lot of data in a small amount of space, that can take a fair bit of abuse before being irrecoverable), shuttling data around without Internet connectivity, still usable for distribution of certain things to certain markets. The Internet is not going to be the be-all end-all of our distribution methods.
