CD lifetime

I've heard that CDs last, at most, 50 years. Is this true? If yes, how exactly does it happen? They suddenly decompose after that period? I can't see any traces of oldness on any CDs, which should appear if the statement is true.

probably means more like wear and tear kinda shit.

CDs will eventually go away as a storage media, like vinyl, then 8 track tapes, then casettes. YOu can burn them on DVDs now. Suspect there will be more advances forthcoming. Damn, I still got the vinyls.

I'll never get anything else than CDs. I love them just like the vinyl generation loves vinyls.

haven't they only been around about 25 years?
i don't see how they could know that, unless cds have a half-life or something

I think they did some "extreme conditions" test that was supposed to include what otherwise would happen over 50 years.

basically, yeah..they break down over time and get "holes" in them. They are starting to notice it in the old school cd's circa 1990. Now given the quality of the CD's have improved over the past 15 years as well, but they are still subject to the same thing over a period of time (probably longer)

I'm not sure if it's UV exposure, or chemical breakdown...I read an article on it a couple months ago...I believe posted here, even.

google it...I'm not interested in looking it up. I'm too scared to find out when I'll lose all my classic choons...

But I have CDs from around that time, and I can't see, feel or hear any sign of decomposure.

Google is your friend.

Wait until they're 20 and see if that still holds true. I've heard of some CDs manufactured in the 1980s that are already going. I guess the only positive thing to say about old CDs that are not 'remasters' is _that_ music actually had care during mastering back then and wasn't the in-out thing it is today where they just try to make the music louder than anything (and squeeze all of the dynamic range out of the music) (some people call this the 'loudness race' and it took place in the 1950s as well).

i red in some paper or smth that the japanese actually found some sort of cd-virus ro smth like that - i know it sounds funny but they can get infected by that sort of cd-fungus and kinda "rot" from that shit... so...

oh noes!
gotta make copies

For me, CDs are nothing more than a medium for transfer from the store to my computer. I rarely play any of my CDs anymore, I just rip them into digital files and play my MP3 player anywhere I would use a CD (such as my car).

It's not like I'm worried I'll wear them out or anything, but it's just easier to carry a little $300 piece of hardware than a huge book containing $1200 worth of CDs.

Yeah

Most of my cds are fucked up from spinning them in sets.

However, i think the quality of CDs has gone DOWN. For example, my Paul Oakenfold Another World CD looks like someone ran over it with a car--plays flawlessly. However, my Bloom CD got some minor scratches on it (I have no idea how, becuase when I wasn't playing it, I left it in the case)...and it skips all over the place.

My Police - Ghost in the Machine CD has really really low sound on it, but its the original copy of it :/

Alot of my older cds from the 80's have lower volumes then the ones made these days, but once you turn the volume up, you can't really tell the difference in sound quality.

I rip all of my cds to my pc, so who knows...

I thought that it was the glue holding the label (and written surface) onto the CD actually decomposes the label causing holes in it. *shrug*

I still buy CDs. I haven't burned anything in almost a year.

The '80s CDs have 'lower volume' because of much better mastering back then. There was more of teh CDs dynamic range covered back then. A climax really sounded like a climax. They didn't squeeze all of the dynamics out of them back then. Music actually had dynamics -- unlike today, where you are liable to pick up 90 % of CDs out and just hear a 'wall of noise' (you can't tell each instrument apart and they're made that way just for radio use). When the dynamics are squeezed out, all of the music in it just sounds like one _sound_. Without dynamics, music can't be what it really is: an experience.
