Hi,
I've made cd quality test graphs. If someone want to check it, there are links:
https://www.intercore.com.pl/cdtests_p95
https://www.intercore.com.pl/cdtests
If someone wants to generate graphs like these there are scripts:
https://github.com/artkar0/cd-tests
In this project I want to see the aging process of different type CDs.
Every few months I'm gonna add new scan result and I'll update the page.
Regards, ArtKar
