Abstract: A carriage assembly useful with a head accessing mechanism in a magnetic disk storage system includes a base having parallel guide rails disposed in a triangular type configuration. The rails cooperate with a carriage body having a first set of bearings for riding on the top surface of the guide rails, and additional angled bearings that engage corresponding angled portions of the guide rails inboard of the periphery of the base. At least one of the angled bearings is spring loaded. The configuration is symmetrical about a vertical plane that is coincident with the direction of the axis along which the accessing mechanism travels.
