Abstract
A strip media drive system has a pair of rotatable strip media packs for reeling the strip media therebetween. An endless belt couples the rotation of the media packs together. A belt tensioner creates a greater tension in a portion of the endless belt leaving than in the portion entering the belt tensioner. The belt tensioner includes at least first and second rotatable rollers. The first roller has a hard outer periphery and the second roller has a viscoelastic outer periphery. The first and second rollers are forced together on opposite sides of the endless belt so that as the belt is drawn therebetween, rolling friction between the rollers creates the higher tension in the portion of the belt leaving the tensioner.
