Storage technology of the future

It is something to do with the "silver" layer apparently. It degrades and flakes. There was a study by US Library of Congress awhile back. The best quality CD lasted about 6 years or so. regards, Paul Watson Ireland Feed Henry! K(arl) wrote: oh, and BTW, CHRISTIAN ISN'T A PARADOX, HE IS A TASMANIAN!

doYou're talking about "home burned" CDs, I presume. I have 20 year old music CDs, and they work fine.

I have a 1997 Oasis CD and it is no longer playable. Actually quite a few music CDs of mine are dodgy. I played them a lot (as they should be) and weren't stored in perfect conditions (as they shouldn't have to be.) The study included that as well and found that industrially pressed CDs did last longer but still only about 10 years. 20 years is a good run, must be some good quality there. Most aren't sadly. regards, Paul Watson Ireland Feed Henry! K(arl) wrote: oh, and BTW, CHRISTIAN ISN'T A PARADOX, HE IS A TASMANIAN!

Ever since I bought a digital camera, I've been archiving the piccies to CD each time the camera gets full, so far I've quite a collection. Now since my son arrived, I've been saving the photo CD's in a box we're keeping for him full of "stuff" - momentoes, my old laptop, our old mobile phones and other odd bits of todays technology etc etc (I call it his "crap" box :)) I reckon in another 20 or 30 years, he might actually be interested in all this stuff, so what will technology be like in another 20-30 years, what will be the storage technology of the day, will he still be able read those CD's I'm keeping for him, or will he look upon a CD much as today we might look upon, say an 8-Track or a '78 gramophone record.

The 100meg 'floppy' that was competing against zip drives? I think the problem was that ZIP was first and more established as a result, and then the falling price of cd burners, combined with the fact that everyone and his goldfish had a cdr drive, completely undermined the market.

CDs and DVDs of normal quality don't last beyond 5 years, so 20 years from now they will be useless. Sadly. regards, Paul Watson Ireland Feed Henry! K(arl) wrote: oh, and BTW, CHRISTIAN ISN'T A PARADOX, HE IS A TASMANIAN!

How long do you think the ink will last before fading?

It very much depends on who made the disc and how it was pressed as well as how you store it and use it. regards, Paul Watson Ireland Feed Henry! K(arl) wrote: oh, and BTW, CHRISTIAN ISN'T A PARADOX, HE IS A TASMANIAN!

My best solution was to buy two 250 gb harddrives and a motherboard with serial ata. I then mirrored the harddrives and stored my data there. That way, if one goes down, you have the other. Plus you can swap them out as technology advances and just ghost from the old to the new ones (Keep your OS on your normal harddrive as to not help crash the important data). I would NEVER keep all of your important data on one format though. Luckily it is much easier to move data around these days. If you bought a dvd burner you could minimize the number of discs you have laying around. But I would still start with a really big hard drive. Two copies for very little effort is well worth it. And many newer motherboards have serial ata with mirroring capability built in.

myBlog [^] | mySite [^]Hi, I think the storage of the future will be something like lightbased disks where data runs whith the speed of light in optic glass fibre, is alway's accesible, something like that and i think the cd will be long gone by then. The stupid thing with cd's is that they did not put them in a permanent case and sold them that way(such as the holder that Apple had at the beginning of the cd-rom stations).

Zip was a joke. I found the SuperDisk to be much faster. Also, it was backwards compatible with regular floppies which people kept using. It doesn't make any sense. But then again, the betamax never took off even though it was better than VHS. "If only one person knows the truth, it is still the truth." - Mahatma Gandhi Web - Blog - RSS - Math

Zip had better marketing and IIRC was out first which gave it a major edge in early adoption. Betamax failed because VHS was 'good enough' and was significantly cheaper because it was an open standard and there were no licensing fees required to build the hardware.

myBlog [^] | mySite [^]I have a box in my closet with a half dozen vinyl LPs at the bottom. My kids think they're idiotic. My guess is that there will be services that will retrieve those images for you (I might even start one right now in anticipation) much like services which transferred old 8mm home movies to video and now DVD (I used to work at one of the first companies to do this well.) On the other hand, looking at old photos can be a real bore fest, even when they're my own. I don't know how many times I've found pictures of some long past event and wondered why the heck I didn't take more interesting pictures.

doWow, that really stinks for me. I have quite the old PC game collection, but sadly they're all on CD. I have games dating back to the early 90's. Most of them amazingly still work on Windows XP, but I have an old 486 just in case. The point is, some of these things have copy protection on them so that you can't copy them to a new CD. You can copy the files to a hard drive, but the copy-protection doesn't transfer so when you try to install from the hard drive, it won't work. What would you all suggest in this situation?

Most copy protection, or old copy stuff at least (I haven't tried it on anything new), can be bypassed for duplication by using a raw mode disk copy app. I don't recall the name of the one I used a few years back though, so you'll have to google around for one.

As stated earlier, CD-Rs have a surprisingly short shelf life, from 2 to 5 years. I believe this is because the info is burned into an ink layer, unlike commercial CDs which are pressed into a silver layer. On the CD-Rs the ink degrades over time. Here are two storage options for your photos: - Buy a second hard drive and be diligent about backups. Of course HDs crash too, so make sure your data is always in two places. My USB backup HD crashed recently... - Subscribe to an online storage service. The storage costs are typically pretty expensive per GB though. Cheers, Doug

Ever seen how nicely orange juice cleans a cd? So clean you can see right thru it! ;P
From personal experience, I can tell you that tape takes care of that nasty opaque problem too - just apply a little Scotch tape, rip, repeat. Makes your CD brilliantly transparent and utterly useless in less than 5 minutes! :doh: The oldest storage (other than hammer/chisel) I can claim is 5 1/4 floppy, but I've got a couple drives laying around. ;) -- modified at 20:59 Wednesday 8th March, 2006

"More than 100 years projected lifetime for DVD-R General" (Verbatim, http://www.verbatim.com.au/technotes/DVD-RGen\_Lifetime.pdf) Verbatim DVDs have a projected lifetime of more than 100 years so all these discs everyone is talking about must be the very cheap ones. It is because of Verbatim's patented Metal Azo Dye Technology; and this is why Verbatim discs are always double the price of everyone else. "In addition, Verbatim’s silver reflective layer is especially designed for best performance and longevity in combination with Metal Azo Dye, whilst our special UV-cured coating and polycarbonate adds to the durability. Due to these superior features an archival lifetime of more than 100 years is projected." (Verbatim, same as above) I know the Laser DVDs also have have Azo Dye and I remember reading somewhere that laser discs are very good too; thats the ones with the azo dye.

You can find apps that will circumvent the copy protection or you can try and contact the producer of the discs and request new copies for a nominal fee (you can do this with music CDs too.) regards, Paul Watson Ireland Feed Henry!
