Strange lines in discs?

so finally, anyone could solve the problem

“straight lines”? They look like drawn with a ruler. Manufacturing errors? Because “burn rings” are around the hole and not straight lines i think…"

the same happens to me sometimes, especially when buning a 4x speed… thnk you

i update my firmware i and try nero, alcohol, record max with the same results

What drive do you have? I sometimes would get some lines on Ritek R02 burned at 8x. Funny thing is I only started seeing them with the 822 and 830 firmwares. 800 firmwares never had those lines.

i have 822 with the last firmware
