Abstract
Data recording tape is passed along guides and past a read/write head. Sensors detect the position of the tape and adjust the guides and the head as a function of the position. If the tape deviates from the target tape path, a controller moves a guide to steer the tape back to the target tape path, using the sensor signals. In cases of tape disturbance such as those involving rapid tape motion, an adaptive estimator uses the sensor signals to position the head to anticipate the expected position of the tape when the disturbance arrives at the head.
