=== Partial constant angular velocity (P-CAV) === If the used media (e.g. [[DVD-RAM]] variants) has a linear (writing) speed limitation that can not be attained with physically supported angular (rotation) speeds at the inner edge of the recordable area, the disc writing can start off with a constant angular velocity, until the increasing linear velocity has reached the writing speed limitation of the disc. At that point, the drive transitions into writing with a constant linear velocity.<ref name=P-CAV>[https://qpxtool.sourceforge.io/glossar.html#p_cav QPxTool glossary: P-CAV (partial constant angular velocity)]</ref> <ref name="cdrlabs-SE208">{{cite web |title=CDRLabs.com - Samsung SE-208GB Portable 8x DVD Writer - Reviews |url=http://www.cdrlabs.com/reviews/samsung-se-208gb-portable-8x-dvd-writer/print.html |website=CDRLabs |accessdate=9 August 2020 |language=en-gb |date=2014-12-03}}</ref>
