I’m not that familiar with RW media. From the scans I’ve seen, yours looks alright. I have yet to see RW media that burns anywhere near the best of +/-R’s. Should be fine … if you have problems, then erase and do it again.
Btw … “quality” and “cheap” media … there are “cheap” media that will show acceptable to nice looking scans, but there’s a lot more to assessing quality of media than just quality scans. Just look at the Ritek G05 thread, and you’ll realize it’s a must to consider long term reliabilty and integrity of the media when you judge quality. Your initial scan just tells gives you a snapshot of that particular moment. Every media will degrade, some faster than others. The risk with “cheap” (referring to known price-to-quality perception) media is you may run the risk of having to re-burn your data due to marked quality loss in a short amount of time. So, in the end, the “cheap” media … gets rather expensive. Just my $.02. Good luck.
