You don't know what you're talking about, I've made the shit. All of the polymers (Google the word as it is above your knowledge level lol) are manufactured into their disc shape the same exact way through the same exact process. I know because I've been there and I've done that succa. Now, are there different grade of polymers? Sure, because each vendor of the polymer has a proprietary compound. That doesn't mean a CDR can't be made from the same exact polymer as a PlayStation game or cd. You just arguing as usual about shit you don't know. You buy crappy cdrs to burn on and chalk it up to all cdrs. The real difference is the imaging of the data. Keep arguing with yourself, I got grown up shit to do.
