What does it mean when dye rings are visible on a burned disc? Is it the result of poor manufacturing or aging (and is degradation faster?)? I'm seeing this on what's supposedly good, albeit older media that's been sitting on store shelves.
MID: MCC 004
Manufacturer: CMC Magnetics (PAPA)
Burn Speed: 8X
When the media is written with a Samsung SH-202J burner, one darker dye ring is visible near the hub. Scans look very good.
However, on my LG burner, I see two dye rings. Scans show a very high number of PI errors for the first 20% of the disc, followed by an excellent looking 80%.
