Burners don't burn a disc the same way regardless of speed. The laser has to heat the disc so the burner changes the laser strength as it burns etc, so there's nothing to say it can't burn just as well at a faster speed.
To my way of thinking the only rule is there isn't a rule. Some burners burn one brand of disc better than other burners. I have Pioneer burner which struggled to burn a Verbatim disc at any speed when I bought it. The quality was just terrible. A firmware upgrade later and it does a very good job, even at 20x. The rated burning speed of burners is a massive case of misleading advertising.
No burner burns the whole disc at one speed, they start off slow and ramp up the speed as the burn progresses. Just because you pick 16x doesn't mean the disc is being burned at 16x. That's just the maximum speed which will be achieved if you fill the entire disc.
I've got one burner which is only marginally faster at 16x than another burner is at 12x because the first burner takes a little longer to ramp up the speed than the second, so it's in fact burning at least some of the disc slower at 16x than the second burner is at 12x.
Anyway, I've owned several different burners over the years, burned hundreds and hundreds of discs and I've run hundreds of burn quality tests. As a result, I only use Verbatim discs the good ones with the Azo dye and I settled on Pioneer burners. I even developed theories I can't actually prove, such as the ambient temperature having a slight effect on burn quality, and I'm convinced after having been through several disc burning marathons, the more discs I burned in a row the more likely the burn quality would be high, and I can only put that down to the successive burns blowing the dust out of the burner Maybe that's why sometimes slower might seem a little better There's absolutely no way you can burn one disc at one speed and a second disc at another, check their quality and know for a fact that one speed is better because it'll vary a fair bit anyway at a given speed.
You really need to check a lot of discs and take an average Which is kind of what I did over time. The newer Pioneer burners seem to do just as well at 16x and I'm convinced at slower speeds the quality drops a little That's just Verbatim discs though.
Changing the brand of disc will no doubt change the result but as I mainly stick with Verbatim I haven't developed any burn speed rules for other brands. There's no doubt though if you use crappy discs then burning more slowly can improve the quality, but there's no guarantee. And of course don't forget the 4GB wobble I've seen quite a few low speed burns still turn to shite around the 4GB mark. Unfortunately there's not a lot of burners on the market these days which can be used to run burn quality tests and I couldn't even tell you which ones can, and you need the software to do it anyway.
So my advice would be not to burn at a painfully slow speed in the hope it'll improve the quality I've got three burners in this PC and I've often burned three discs at a time and I still burn at a minimum of 12x. It's very possible a particular burner might do better with a particular brand of disc at a slower speed, but it's very possible it also won't.
PS I tried a spindle of Taiyo Yuden discs at one stage, just to see what the fuss was all about. They're fairly expensive where I am and not easy to come by, but I thought what the hell I pretty sure my Pioneer burners burn at a slightly higher quality using Verbatim dics than they do with Taiyo Yuden. There wasn't much in it, but I went back to Verbaitm.
Well, I've just gotten my Verbatims and burned a set of almost-perfect discs, no coasters and ImgBurn success jingles every time. BUT, one of the burned discs has noticeable banding near the middle of the disc, like the burn was uneven.
Should that be a cause for concern or should I just not be worried about a physical inspection like this? Age of 16x DVD media. When DVD burning technology was developed, CD burning had just hit its prime with 16x speeds and BurnProof technology with decent buffers.
For years, consumers whined that DVD burning was too slow, as compared to CD regardless of the storage size differences , so 16x has long been a goal of drive manufacturers. And this is probably where speeds will stop. The main drawback to this now-achieved goal, is that it seems rushed, given the experiences of those who routinely attempt 16x burning.
Even high-grade media like Taiyo Yuden and Mitsubishi is not immune to this problem. DVD recorders are most affected, with their 1x real-time recording method. Most 16x media is not true multi-speed media, so burning at 1x yields a high coaster count, assuming the machine will even acknowledge the blank disc. Quite a few DVD recorders, even ones purchased as recently as , are known to reject 16x discs, refusing to even see the blank. All you really have is a big assumption based on old information.
To my suprise this forum has centered around high writing speeds, which some years ago was considered not to produce best results, that inspired me to open this thead. I hoped someone can provide new information or interesting web links. I would not dream of burning at lower speeds. Years ago both the media and the drives were still a very young technology, therefore both the industry and the users were still on a learning curve.
This has leveled off a bit as the media and drives have improved, but the release of new firmwares to fix problems shows that the learning is still happening. I agree that high speed seems better in most cases - for certain disks a quality scan of them burnt at 8x is much worse than one burnt at 16x.
Thanks for your suggestions. I found also some more answers to mu high speed DVD burning hesitations…. Home News Reviews. This is document adme in the Knowledge Base.
