I have copy of Nimbus Records Elgar Nursery Suite NI7029. I bought it new. I play it occasionally, and it has always played well. When playing it today there was a distinctive "bumping" in the background. On close examination of the disc, I noticed a shadow which I could not remove by cleaning. It would seem that the "shadow" has appeared between the metal surface and the plastic coat. The disc is in a set of four, and one of the other discs has developed a similar mark.
Someone will probably tell me that this well known phenomenon is caused by storing discs along the axis of a layline, or under a power cable, or that it's a sign of radon gas contamination, or just metal fatigue, or plain oxidation.
Has anyone else had this problem? Does anyone know why it is happening? How can I protect my 1000 silver spinners?
