The Last Post Game!!!!

I find great differences between CD players too. I have to keep in mind sometimes which CD to put into which player.

True, but if there is a transparent gap in the CD that you can play "How many fingers am I holding up?" through, I'm fairly convinced that I can visually identify the problem. Also, (as far as I am aware) this has only happened to three CDs out of 650-ish that I own, and they are all the earliest ones that I own: one is a Chess Records compilation copyrighted in 1989 but probably bought 1990 or '91; one is Sinead O'Connor's "I Do Not Want What I Have Not Got" from 1990; and the last is one of my favourite albums of all time: "Rumour and Sigh" by Richard Thompson from 1991 (which I have replaced, obviously).

Hm, maybe I should check some of our oldest CDs.
Mussorgsky's Pictures at an Exhibition is the first I can remember.

if there is a transparent gap in the CD

That has only happened to me with CR-Rs.

[Swatopluk]

There is something called DVD rot. I assume that affects CDs too.

For what I read it's basically what we have been talking about, specifically regarding the reflective layer which in certain cases becomes susceptible to oxidation/degradation.

Last _{as for the data layer itself the expectation is between 25 to 100 years} Post.

Please call someone in 2100 to tell us, whether this prediction turned out to be true

It wouldn't be surprising if 50 years from now there is a mad dash to rescue all the data in degrading optical disks.

Last _{perhaps sooner} Post

[Swatopluk]

An updated version of the book rescue. The switch from cloth fibres to wood fibres treated with sulphate turned paper from lasting for centuries to a few decades. And some older manuscripts suffer from the ink turning to hypercorrosive stuff over time (e.g. the J.S.Bach autographs)

Last _{we will have to return to clay tablets one day or put up with the losses} Post

[Griffin NoName]

Clay tablets, or indeed writing on them, are not indestructable. We will have to find some chemical/nuclear solution.

Last _{personally I doubt anyone will still be around in 2100} Post

[Swatopluk]

Nothing is indestructable but of all data storage methods as yet deviced by man the clay tablets have the highest life expectancy (>100K years) when not disturbed.

Last _{even rock carvings fare slightly worse} Post

[Griffin NoName]

even rock carvings fare slightly worse

But not cave paintings.

Last Post

[Swatopluk]

But only if few go to watch them, they turned out to be quite sensitive to change in the microclimate.

Last _{as a result most of those caves are now closed for regular visitors} Post

[Griffin NoName]

Even regular bats?

[Sibling Zono (anon1mat0)]

I wonder how long will those laser edged 3D portraits will last.

Last _{that could potentially last for a loong time} Post

[Griffin NoName]

Nothing is going to last for a long time. We are all doomed.
