generally only the cheaper disc manfacturers have this issue. I have several discs from the early 80's and they all look and play perfectly. 40 year old discs, and perfect.

And I expect virtually all the good ones of that age have clear plastic surrounding the center hole. 95% of problems came from early european CD manufacturing specs that allowed the center hole to be cut through the disc without a central clear plastic buffer to cut through (Japanese pressings had the plastic buffer from the very start). So it was more like a Philips (most European manufacturers) specs v Sony (all Japanese manufacturers) specs issue (with both of them being co-inventors of the medium) rather than individual manufacturers being cheap. There were other issues contributing to bronzing too, but the center hole design problem was the major one early on.
