I have used this media code, it can vary greatly in quality from results such as those above to coaster after coaster at the edge of the discs. About 3/4ths of them from 3 or 4 brands worked very well, while the other 1/4th had disappointing performance (batch by batch variations in quality in my experience, not from disc to disc). It’s not specific to that drive by any means, I have several burners that produce results like that with these discs when they are from a good batch. I don’t trust Optodisc’s track record for stability much though based on their early media, although I haven’t observed problems with mine as of yet so perhaps it’s not an issue with their later media. One concern with most of mine is that although the scans of many of the discs were generally quite good, there was often a rise in PI near the edge as well as a more PIFs towards the edge at times (sometimes only very slight, sometimes quite noticeable), so again I am not confident in their long-term stability especially as it’s towards the edge.
