  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

1.6 terra bites per disk.

heres a link from engadget that is a bit easier to understand too: http://news.bbc.co.uk/2/hi/science/nature/8060082.stm

It's similar in concept to holographic storage media. But rather than using multi-faceted write surfaces, it uses a media that actually accounts for different laser properties. Interesting concept, but it seems to me that the media with the high concentration of position-specific gold rods would be prohibitively expensive.
 
It seems like we always hear about this type of technology, and then it never materializes.

The funny thing is, many of the biggest technological advances that we see now never really had any advance fanfare.

Ten years ago a one Terabyte Hard Drive just seemed like a ludicrous notion. I remember reading an article where IBM researchers said they had developed a technology that would allow a 3.5" Hard disk to record up to 100 Gigabytes, (!) but the catch was, there was no possible way of playing back the data! Then, a couple of years later somebody discovered Giant Magnetoresistance, and now One Terabyte drives are becoming old hat.

I don't think anybody predicted how huge and cheap flash drives would get. Anybody remember floppy discs?

Nobody predicted how cheap and good flat-panel displays would get, and how fast.

To say nothing of the tri-color laser.
 
I refuse to be impressed with ANYTHING like this until everyone's roof generates solar power.

Most definitely. But this is a sort of proof of concept. Other cheaper materials and manufacturing techniques will follow closely behind that exhibit similar properties. They mention they could hold up to 7.2TB if they added another orientation or polarization. I would add they could add several extra orientations of polarization (180 degrees to work with) and are only restrained by read-write error statistical issues.

Of course this is way out there, but dare to dream!
 
The original disk was the blue disk invented in the 80's at Australian National University. It could theoretically have stored millions of frequencies per spot on a rare earth recording layer. This meant that a CD could theoretically store something like millions of times more information, puts BR and holographic to shame. The problem, well it was called the blue disk for a reason, when exposed to light it turned blue and erased previouse information. I believe the technology was eventually used as a disk cache (non disk optical memory) for servers, that went between a hard drive and regular memory/cache. I could probably use it, I have been tinkering with ideas for method to produce the frequencies (but only a limited amount of frequencies at a time) and I have a method to prevent it from being accidentally erased It probably could also be applied to one of my other storage projects, a new tape system, that can have orders of greater density than Holo disks.

Unfortunately, it wont be suitable, I remembered something else, the information used to dissipate after an hour or two, I think. Well, at least I could use it as optical memory, though optical memory design can be problematic, most techniques I have accessed are too slow (and from memory this one is too).

I'm just waiting for the 100TB storage devices that are priced around the price of a 100GB hard drive
