I bought Philips dl dvd+r before from OTV with a printable top, and those were way better. These ones with a silver top seem to have way less reflectivity. Mind you, they are from the same manufacturer and have the same media ID CMC MAGD03@ (CMC Magnetics Corporation)
Nero Discspeed gave these silver top discs a 53 percent (terrible and will wear out your dvd player or pc's laser).
KProbe2 told me that right around the layerbreak the disc has a huge spike in its pi, the best results i got were this:
PI Max : 211
PI Average : 27.82
PIF Max : 4
PIF Average : 0.13
But most of the discs i burned had a PI Max of 400+. you are looking for around 100 as a max.
the printable top ones with the same test
PI Max : 69
PI Average : 8.78
PI Total : 246920
PIF Max : 4
PIF Average : 0.28
PIF Total : 7985
if only i didnt waste the 20 bucks on these silver tops. guess ill stick to verbatims from now on
