I recently bought a 25-spindle of Ridata 4X DVD-R Ritek G04 and a 25-spindle of Ridata 4X DVD+RW RICOH JPN W11-01 from Amazon.com and I noticed that both spindles were the ugliest looking spindle of discs I have ever seen. The edges of the discs are very bumpy. Polished... but nevertheless bumpy. When the discs are stacked up in a spindle of 25, you can really see imperfections in the edges of the discs. Individually, you can feel (harder to see) the bumpiness on the edges. I checked out other brand DVD-Rs and CD-Rs and I can feel ever-so-slight imperfections on the edges of these discs. However, not to the degree of the new Ridatas I recently bought. Has anyone else noticed this on their Riteks? Are these discs defective? So far, they burn well and they are working for me. But, I've only burned a few from each pack. At first, I was afraid that the imperfections in the edges would cause excessive disc wobble in the DVD burner/players. Again, they do seem to work okay. Just a shocking observation. Any thoughts?
