Abstract
A vibration damper for a transducer positioning system of a diskette system employing a stepping motor for driving a moveable transducer carriage that is coupled to the stepping motor drive means. The mass of the carriage and the coupling means form a vibratory system having a natural frequency of oscillation significantly different from the frequency of the pulses applied to the stepping motor so that while the motion of the carriage reflects the total motion of the shaft, the incremental motions of the shaft are not transmitted to the carriage thereby minimizing noise ancillary to the positioning of the carriage.
