1TB Blu-Ray Compatible Optical Disc Announced
red_dragon writes "An article on The Register tells the news of an announcement of a new 1TB optical drive and disc that will be backwardly compatible with Blu-ray discs. The technology, developed by Call/Recall in partnership with Nichia, uses a rhodamine-type dye in a 200+-layer recording medium that gives off light when excited by a laser beam, along with a single fluid-filled lens to read multiple layers by varying the amount of fluid to change the focal length. The technology is designed to work with Nichia's blue-violet laser diodes, which are already used in Blu-ray drives."
Presumably the correct phrase is laser recording medium?
Awful UID - but I have been here ages...
It's hard to imagine a single movie on a 1 TB disc. At first glance it looks like it will make backing up a cinch. But most of my burned CDs and DVDs start flaking after just a couple of years, unless they can make these ultra high capacity formats more archival friendly it's just going to be wasted space.

That these Blu-ray compatible discs will be primarily used by consumers to store ripped Blu-ray movies.
If someone says he and his monkey have nothing to hide, they almost certainly do.
How many libraries of congress could you hold on that?

100MB/sec? Assuming that the capital "B" is the intent, that means it would take close to 3 hours to write a full 1TB disk. Is that fast enough for most backup applications? I mean, obviously it would be fine for archival purposes, but it doesn't seem practical for daily backups.
Unless you're doing daily backups of Libraries of Congress, then it should function just fine. :)

And I thought I wasted my money buying a HD-DVD writer. Now I've gone and wasted my money on an ordinary Blu-Ray writer.
Alright, I lied. I didn't buy either of those. In fact, I'm not going to buy this "rhodamine-type" enhanced backwards-compatible Blu-Ray drive, because that will soon be surpassed by a Super-deluxe backwards compatible "rhadamine-type" enhanced backwards-compatible Blu-Ray drive. To think I thought the race was over.

And for you, only a DVD is required to store your mental state.
I'm stateless.
Hell is other people's code.
All right everyone, the old Blu-Ray is obsolete! See how crappy the puny 1080p looks on your pathetic Sony widescreen? It is time for NEW-RAY.
Throw out your entire video library once again and embrace NEW-RAY.
Que?
I'm interested in. How reliable and/or affordable will these things become, should the product achieve decent market penetration?
/. blurb and saying, "Hmm...Interesting."
Zip Drive was a high-priced novelty that achieved just enough marketshare to ruin a lot of people's day with the "click-of-death" issue.
It's taken years for CDR/DVDR media to become reliable and cheap enough for commonplace usage.
As has been previously mentioned, reliability is also a major factor to take into account. I want a backup that I can rely on should I need to retrieve information from 10 years ago (at a minimum)
I have some CDRs that I wrote to in the late 90's (around 1998) that are now becoming unreadable due to "whatever". They are not scratched, nor is the aluminum layer at the top flaking off, yet they are simply unreadable now, so I find myself duplicating CDRs that are still readable "just in case"
If reliability ratings for the media can surpass normal CDRs by a significant amount, I may be interested in this format, even if the price tag on media is steeper, once mainstream acceptance is achieved.
Right now though, It's little more than reading a

We keep having excitement about great advancements in mechanical storage. WHY?!?!?! If developers could stop leading us in the wrong direction because it excites some by huge numbers, perhaps we could focus more on faster static memory and get a 1TB on a chip...that won't were out...that won't die when scratched...that can have high transfer speeds... Anyone else out there tired of looking at last decades technology getting bigger and faster and want to head down smaller, cheaper, faster, stronger, less mechnical...
jsut athnoer menagiensls ltitle psrhae for you to dcoede. Why do we wtsae our tmie dnoig tihs?
...so more of the same crap? I have tapes the size of my face that still work flawlessly, and actually get used every once in a while for retrieval of archived data. All my server backups are on tape, and all of my cluster backups are on tape. After three years of constantly writing and swapping tapes, I haven't had a single DDS4 tape go bad on me. The number of CD and DVD coasters on the other hand...
Nope.
For a pressed DVD, a master is etched, and is then used to physically press the pits into the substrate. The depth of these pits (1/4 wavelength) causes destructive interference when the beam hits a pit, and constructive interference when it hits a land. (1/4 wavelength in + 1/4 wavelength out = 1/2 wavelength out of phase with the rest of the beam reflecting off the surrounding substrate)
This is pretty much permanent, provided your media doesn't disintegrate.
For a burned DVD, a photosensitive dye is activated by the writing laser. This activated dye simply absorbs the beam that hits a "pit", while the unactivated dye allows the beam to reflect off the substrate behind, when it hits a "land".
Over time, this dye can degrade such that the unactivated dye slowly activates (either spontaneously or in reaction to ambient light), or that the activated dye slowly deactivates for the same reason (much like a photo left in the sun).
One of the reasons that "archive quality" disks are more expensive is that they use a higher quality dye which takes longer to degrade.
The nice thing about "mechanical" storage (since when was optical storage "mechanical") is that it is cheap. The amount of storage space on a hard drive has more than outpaced Moore's Law. Optical media hasn't quite kept up with that sort of spectacular growth, but there have been significant advances there too. In my eyes, anything that promises cheaper (in terms of $/GB) storage can only be a GOOD THING.

Dear Mr, Smith,
What is the value of information?
Does the value of information (per bit) decline as we gain the ability to store more information?
If not then presumably one of these disks ought to be worth a fortune if a Floppy was worth anything. Should they have scratch proof containers?
since this is not the case, one assumes the value of information to humans is declining with time?
Does this mean what a given person knows is also declining in value, or are we discarding information from our brains that has less value. If so then why do you still remembers that Speed Racer's little brother's name.
Eventually we will be able to store the neural state of any human. At that point if someone were to invent a method of reading out this state it could be recorded onto a Disk and preserved after death. Like Cryonics this disk would then await a time in the distanct future when the neural state could be restored from the disk to clone or simulated human.
Actually, that was just the long winded way of explaining to you Mr Smith that when we were restoring you from your disk we noticed a small scratch on made by an heir you stiffed in your will. We're pretty sure the amount of information loss is small however, though were not sure what it might have been.
Sorry for the inconvenience and thank you for selecting TotalRecall. Your bill will be in the ether.
Some drink at the fountain of knowledge. Others just gargle.
