You are welcome.
In the context of CD-R, jitter tends to mean one of two things.
Inconsistency in the pit/land edges written/read from the CD - and high speed writing often exceeds the standard threshold for this on CD-R
Audio jitter (not common now), where the drive was unable to reposion accurately after pausing, so many CD ripping programs carried out “jitter correction” by commencing each read block overlapping the previos one, and matching them up. Most modern drives support “accurate stream” and no longer require this.
