Really strange burned cd

My English is not so good but i try to explain.
I’ve a liteon burner (40X12X48)
I use Nero
And the Recordable that i use is a 40x platinum.
I burn 700 mb’s of data on the cd.
If i look to the place where it’s burned i see a thick burned place and a thin burned place ??? The circle in the middle is verry thick
and the other place is verry thin???
Really strange. It happens with every cd.

The burned surface may not look the same due to not writing at the same speed across the whole disc. (it starts writing at about 19-20X and finishes at 40X).

This is normal and is nothing to worry about.

You may check if you have the latest ZS0K firmware, if not…upgrade :wink:
