CD-eating printing inks

There has been some oxidisation problems on certain discs. The discs were going brown at the edges.I can't remember which off hand. A search might find the thread.

I have an ASV CD, made in England, from 1990 which has gone yellow. Still playable though.

I bought my first CD in 1988. Since then, one disk out of my collection of 100's started skipping inexplicably and had to be replaced. The rest are fine, some after 17-18 years. Fingers crossed.

I don't know if it is a matter of corrosive ink.
The fact is that after years and years some of my cds (perfect with not even a finger print) start acting strange.
They said: a cd is forever.
I say: don't believe the hype.

I have a friend who mocks my 'old fashioned' cd and vinyl collection saying HD storage is the future and "forever".

How I laughed when his 3 yr old HD inexplicably stopped working and is indeed beyond repair.

The same bloke always asks where the bass is on my system. Basically because its not shaking the next door neighbour out of his bed. Horses for courses I s'ppose.

Yes.
Music for machos!
Same problem with surround systems.
I went to see a guy, some months ago, and he delighted me with his new bloody system.
I did have to escape.
My ears and my head were hurting.

He could have avoided that disaster by backing-up each of his recorded albums to quarter inch tape and storing these in a fire proof aafe

I could never find the loudness button on my amp either.

"Loudness button" is one of the most incredible cheats of audio market.

Sorry Mike.

I was talking about japanese stuff.

I have a problem with Nimbus CDs from the late 80s / early 90s with the disc coating going soft and tacky on the label side. You can't clean fingerprints etc off them, as this makes it worse. I think this was known about at the time. I have a few hundred pounds worth of discs like this. Has any one else experienced this, so far all of the discs are playable, but I would like to know, does it eventually affect the playback of the disc?
I have only had a few with the famous CD rot, mainly singles. I heard this was due to pressing plants not sticking to the red book specs, taking the metallic layer right to the edge of the disc. This then allowed the layer to oxidise, hence CD ROT! Red book spec called for about 1mm of plastic substrate beyond the metallic layer to effectively seal it from the environment.
