Hey… what does it mean to your disc if you get jitter errors?


I have moved this thread to the Blank Media (parent) forum, where more people are likely to see it and respond to it.

@ForeverLearning, I think it would help if you were more specific in your question.



What I mean is when you run a disc quality check, it has an area for jitter… what does it mean when you actually get a percentage in this area rather than nothing?


If you get nothing, then your drive doesn’t report jitter. if I remember correctly, only some Benq drives can report jitter with CD/DVD speed.



Oh… so what does jitter mean?


Have a look in this paper (PDF format):

Jitter, what it is and how to measure it

A rule of thumb when scanning for jitter on a BenQ drive is that you want jitter to stay below 12% (not counting random spikes that result from the scanning speed “dipping” at certain points).

There is some discussion whether BenQ correctly reports jitter when scanning discs not burned in a BenQ drive, but no final conclusion has been reached on that subject.


There is a very experimental beta tool that makes it possible to scan for jitter on recent LiteOn drives with experimental firmware. See this thread if you’re interested.

Plextor drives can also scan for jitter, but they don’t report an absolute jitter percentage, so they can be hard to interpret.


Okay, thanks.
