What The Hell

Just bought a 25 pack of datawrite yellow dvd-r 4x Ritek GO4

here are 3 scans from 3 different discs from different parts of the pack, is it just a bad batch? or are the datawrite ones crap?

i burned 2 good GO4 discs that i bought just to test but they were from a different brand, all ive done to my burner since then is to use omni patcher to enable 8x reading and apply the recommended changes, i left all other boxes unchecked, i burned a couple of different brands and they burned the same marginal as usual but no stupid spikes like this

any solutions guys?, looks like ritek g04 is the best brand i can get round here
