ABSTRACT:
Positioning apparatus for moving read-write transducers in data record systems achieves improved stability in the motion and positioning of such transducers with reduced complexity of structure compared with known apparatus of the prior art. A particular structure, including a female dovetail guide surface and a plurality of cooperating sloped guide wheels, one of which is spring-loaded for force balancing, causes a plurality of reference guide wheels to maintain firm and stable contact with a smooth and flat reference surface and assures the desired stable and accurate movement of the carriage.
