ABSTRACT:
The focus actuator, turntable and translation stage in an optical disc record/playback system may effect relatively large reaction forces on the components of the system. These reaction forces can cause vibrations which interfere with or distort information recording or retrieving operations which occur at the same time that high speed access is being effected. A momentum compensating mass is coupled to the focus actuator, turntable and other moving elements to reduce or eliminate the reaction forces which can affect system operation.
