Abstract
An optical tape recorder uses a resonant flexure scanner to scan across the width of optical tape in a straight or nearly straightline. The use of flexure eliminates bearings in the scanner design and lowers cost. High data rate is achieved by using a multi-channel laser diode array for writing, imaged by a single moving lens mounted on the scanner. The use of a highly resonant scanner enables to interpolate the position of the lens by knowing the amplitude and frequency of the scanner. The flexing part of the scanner is a single flat spring or a combination of flat springs arranged to generate linear motion.
