Abstract
The position of one or both edges of tape, such as magnetic tape, can be determined using a light source, such as a solid-state laser with a collimated beam, and a detector, such as a photodiode. The tape, by blocking a portion of the light, affects the amount of light reaching the detector. The detector generates signals as a function of the position of the tape. In the case of two detectors cooperating to measure the positions of opposing edges of the tape, the signals from the detectors may be processed to produce at least four useful signals, including a signal that is a function of the tape width and a signal that is a function of the position of the tape centroid.
