A linear actuator for a removable cartridge magnetic disk drive includes a center guide rail on which the actuator carriage travels. Bushings and the motor coil are spaced symmetrically with respect to the heads so that the center of mass, center of friction, center of force, and center of stiffness of the carriage are all aligned along the center rail. An outrigger travels on another rail to prevent rotation of the carriage.
