Extremely worried here...

The first CD I ever bought (even a little while before I had a CD player) still plays perfectly, even with the slight scuffing that is on it. It must have been about 1987 that I bought it (showing my age).

When they were first released they were billed as being virtually indestructable. I still remember seeing Tomorrow's World on TV here when they were showcasing this new technology. The presenter was spreading jam or marmalade on the discs, then wiping it off to show that they could even be played afterwards.

Whilst they are not as hardwearing as we were at first led to believe, if you take even only reasonable care of them they will last you many years. They do deteriorate over time, but I have not yet had any problems apart from slight discolouration of one or two (they tend to develop a bronzed tinge).

One other thing, take care not to damage the printed side of the disc as that is the easiest way to damage them, the recorded surface is only just under the surface...

If it turns out that they do all diminish too much over time, then I am fucked... I am several thousand CDs by now. You think you don't want to be rebuying your entire collection! :ill:
 
The problem with saving data on a CD/DVD is a well known problem. A Cd can`t last forever. I don`t have any exact info about this but this IS a very well known problem.



"What is the lifetime of CDs, diskettes, ZIP disks, hard drives, tapes, etc.?

Professionals working intensively with diskettes and hard drives tend to trust them for only up to five years before they feel a need to copy the data to a new medium or to a new unit of the same medium.

The lifetime ranges of certain media under standard storage conditions (23°C and 50% relative humidity) are:
  • Read-only CDs (factory stamped): 5 to 100 or more years depending on disc manufacturing quality
  • CD-Rs (Compact Disc Recordable): 5 to 200 years depending on disc type and manufacturing quality
  • CD-RWs (Re-Writeable): 5 to 100 or more years depending on manufacturing quality
  • DVD, DVD-Rs, DVD-RWs (Digital Versatile Disc, Recordable, Re-Writeable): not much data is available for DVDs, but its lifetime is generally expected to be similar to that of a CD
  • Tapes: 10 to 30 years
  • Diskettes and Hard Drive: 5 to 15 years
Storing diskettes in hotter and more humid conditions than recommended will reduce the lifetime ranges stated above; cooler and drier will extend their life.

The lifetime of the media is one aspect of longevity; the life or popularity of its playback machine is quite another. The media may survive for 100 years, but the technology to play the media may have disappeared in that time. Replacement machines might disappear from stores before you have made the change to a new format - for example, 5.25 inch diskette drives are hard to find nowadays."

"The media will have become obsolete long before the data have decayed. That is, CD-ROMs are our longest-lived media now (a century has been claimed), but the CD is already becoming obsolete. The specifications for the replacement technology, the DVD, include a requirement of backward compatible, but what will be the next storage medium? The CD, after all, is only a few years old. Of course, even useable CDs will have files that are inaccessible because of changing software within a couple of years."

THE FUTURE


"It looks like a transparent little bit of crystal but changes into a extremley effective storagedisc when lightened with the right kind of laser. the crystal can storage up to 1 Tbit per cubic centimetre." (translation by me..i know..i suck.)

the rest of dream theater = nerds, but still awesome

So what Mike is a bit of a nerd, i mean he has a fucking huge record collection, that is kinda nerdy.

Dt are good musicians they arent good song writers, which Mike is.

I look after my cd's, i hate when cd's skip, i rarely lend them out cuz i dont trust people to treat them with the same respect i do.
 
As far as i am aware Valtiel CD's are fine if you take care of them. And you have an ace name by the way.

I have heard that CD's do not last longer then five years, is this true???

Yes, that is why my Korn - S/T CD is still working, because it didn't come out in 1994, and my brother didn't leave it in our basement when he moved out....
