Abstract
PURPOSE: To control a reel smoothly at all times by discriminating the moment of inertia of a reel for VTR by the ratio of the tape roll diameter and the frictional force of a tape running route by the tensile speed of the tape as well as discriminating the tape running direction and setting the brake force based on these discrimination signals.
