Air pressure between a tape and an air bearing tape guide is sensed by a pressure transducer to control the tape tension in a reel to reel drive. In one embodiment three air bearings guide the tape through a U-shaped path. The center air bearing guide includes a pressure transducer in the guide that monitors the air pressure between the guide and the tape as it passes the guide. In a second embodiment a pressure transducer is located along the path of a compliant air bearing guide.
