I burnt 3 cd-rs (verbatim inkjet printable 700mb disc 1x-48x) at 8x, the scan below (I'm aware that the 4551 isnt that good as a scanner, but I think its safe to assume that if the NEC says section x of the disc is worse than section y, then another drive would also scan section x as worse than section y).
The problem is from the 70min mark onwards, there is a jump in PI errors. Does it use Z-CLV at 8x?
I would like the end of the disc to be the same as the start, so how would I make it burn at a slower speed eg 4x? My old cd writer did these discs at a minimum of 4x. MediaCodeSpeedEdit only changes dvd codes. Any ideas? Or any suggestions? Or am I just simply burning too slow?
Overall, is the disc burnt at what you would consider good quality? The speed graph is smooth right?
