And LaserDiscs can do either! Each one has advantages/disadvantages. CLV has longer runtime, but CAV has better quality and crosstalk properties


one frame is one revolution, so crosstalk from adjacent track is just crosstalk from +/- 1 frame, and it's "the same part of the frame" in a sense.

CAV also allows for clean pauses, as it just keeps reading the same frame over and over again, with no need for a fancy buffer.
