I’ve noticed on about 10% of my DVD-R burns I get “Burn Rings”. They’re not too noticeable but if you look at the disc closely you can see them. Weird thing is that I never get these burn rings on my DVD+R burns, I only get them on my DVD-R burns. I’m using MXL RG03 and Taiyo Yuden TY02 8X discs on an NEC 3520 burner. I’m burning these discs at 4X and I still get the burn rings. Do these burn rings affect the quality of the burn and should I be getting them at 4X?
