Last year I bought a whole stack (200 discs) of CD-R media because the price was low and I tested a few first and they gave really good PI scans (very low PI).
So at first this media was really good, but now I find that they are very fragile discs. In particular on the top surface where they seem only to have a very thin silver layer that sometimes can scratch off very easily.
I was just wondering if anyone else has seen this type of problem before. The discs are just plain silver colour on top, with no printing or branding. Looking at the top it doesn’t look like normal silver paint, it’s silvery but with kind of like a moire pattern (or perhaps diffraction pattern is a better description). Does anyone know the type of look that I mean?
Anyway I’m starting to think that these discs were never made properly in the first place. I’m thinking that they were perhaps supposed to have another layer of clear-coat or whatever to protect this silver layer. Has anyone ever come across CD-R media like this before?
