Abstract
A method and apparatus for controlling the spacing of actuators within a common carriage or frame of a multiple actuator device is provided to render the actuator spacing insensitive to thermal deviations occurring among actuators due to variable thermal conditions within the carriage or frame. A first fixed actuator is connected to an underlying carriage or frame supporting a plurality of actuators and to each additional actuator via links of at least two dissimilar material, such that the respective coefficients of thermal expansion of the dissimilar materials enables the actuators to maintain their original spacing with respect to one another regardless of the thermal conditions within the carriage or frame.
