Just something to be aware of if you still value your CD collection.
...Going through a loft box of CDs that had not been played for ages I noticed that a couple of discs
that were once silver coloured had turned to a gold colour.
If you value a particular CD then this to alert you to the fact the CD is rotting. Once you play the first track you will think there is nothing wrong ..but try and play the last tracks and these will probably be gone and as time progresses the losses will creep on until it is probably totally unplayable.

Just a thought.. are they PDO pressings, Peter? The reason I ask is that this was a fairly common occurrence some years back with PDOs.. for a while the plant offered a replacement, free of charge, for any of their pressings that had turned gold and were not playing as they should; apparently this was caused - allegedly - by the printing ink used on the booklet which then reacted with the disc coating. I had two replaced FOC, one was the compilation "Vertigo "Classics And Rarities" which was pressed in 1990, and the other was an All About Eve CD, but I can't remember which one. Both were Phonogram label discs.

I think there's a useful thread on Roobarb on the few Network discs which are prone to this.
(I'd provide a link, but I'm fully excommunicated from the site; not even allowed to view the homepage!).

DVDs can go through something similar. I had a few delaminate and had to replace them. Mostly Warner titles in my experience, including NTSC Doctor Who DVDs.

PDO discs were the worst in the world. Even worse than their Audio CDs were their CD-Videos. "Gold" (i.e. orange) tinted Laserdiscs. The dye used in those rusted within a year or two unless they were stored in an almost total vacuum.
