Abstract
In a web drive apparatus in which information is written into or read out of a web intermittently movable between a web supply reel and a web take-up reel by means of an information exchange station, a web tension control signal to be applied to a motor for the web take-up reel is compensated so as to suppress vibrations of the web which may be caused during the intermittent movement of the web.
