Why do CD’s skip?

CD players must position their optical system very precisely, relative to the spinning disk itself. It uses very sophisticated electromechanical devices to keep it in place. But if you jar a player violently enough, it will lose its position and the audio may suffer. Most modern CD players save a short amount of information so that they are reading ahead of where they are playing. Even if they lose the track for a few hundredths of a second, they have enough music saved up that they can keep playing continuously. But if the upset is severe enough, they will run out of saved music and will go silent for a moment or two.
