Burn Rings - Do They Affect the Burn Quality?

[bbanderic]

Hi All,

I've noticed on about 10% of my DVD-R burns I get "Burn Rings". They're not too noticeable but if you look at the disc closely you can see them. Weird thing is that I never get these burn rings on my DVD+R burns, I only get them on my DVD-R burns. I'm using MXL RG03 and Taiyo Yuden TY02 8X discs on an NEC 3520 burner. I'm burning these discs at 4X and I still get the burn rings. Do these burn rings affect the quality of the burn and should I be getting them at 4X?

Thanks

I used to get them on some media at certain burn speeds but did not seem to affect playback. Maybe you should scan the disk in question with NERO CD/DVD Speed located in the NERO Toolkit if you have it or use InfoDisk to run and error or speed test. It should show you if there are sections that it has trouble reading.

One theory I had but may be wrong is that these so called rings were caused by burners that did not burn at a steady data write speed from begining to end. My 16x burner when set to 12X for example, will actually begin to burn a section at 4.1x then about 1/3 of the way in it accelerates to about 8.2x and the last third burns at 12.3X. That's what my NEC 3500 DL 16x drive does burning ISOs with Decryter. I can easily imiagine each section looking a bit diferent and so giving the apearance of distinct rings.

If they are still occuring at 4x then I guess that blows my theory. At least on my machine, if I burn at 4x they would disappear. That only happened with certain media and not with others.

It depends. From the sound of things, these are just Z-CLV rings, and are fine. The other kind of ring is a dye error, those are bad.
