My 8x writer has been a serious disappointment.
Attempting to burn anything, on any make of disc, at faster rates than 4x creates a lovely - but expensive - coaster.
The problem arises at each section of the disc where the writer need to gear up to write the next section at the higher speed (4x -> 6x -> 8x).
When the speed changes, it burns a discoloured band aprox. 2-3mm in width. Any file or data within this band is completely unreadable in the NEC itself, a Matsushita SR8585 and a Samsung some-thing-or-other 16x player I can’t remember the model number of.
I’ve taken a picture of 3 coasters it made for me this evening. These are Verbatim 4x DVD-R Mitsubishi Chemical MCC02 reorder # 43247, but even “proper” 8x discs do the exact same thing.
From left to right, the 2 first are burnt at 8x, the last at 6x. The ledgends should pretty much be self explanatory.
Anyone else seen this with their 8x NEC, or is it just my writer that is FuxX0red?
