I am sorry to tell you that you are wrong! Regardless of your belief that you are an expert in this area, I can show you a few CDs that are more than 20 years old. As to your CDs that deteriorated, well, not sure what they were or how they were made, etc. But all I can say is I have a large CD collection many of which date to 1983 or so. So all I can say is you must be very rough on your CDs. There were some issues with early pressings but these were resolved. Today's commercial CDs will last many years.
OK. So now I am ready for you to tell me I am wrong because you know someone who knows an engineer, who test a CD for someone's company...yada yada yada.
