Abstract
The present invention relates to an optical media system () for suppressing externally induced rattle of an optical media pickup. The system () comprises: an optical pickup () for reading from and/or writing to an optical storage medium (), the optical pickup () having one or more sources of light (), an objective lens (), a focus and/or tracking actuator () for moving the lens () to focus and/or track the light on the optical medium () and mechanical limits to limit the focus and/or tracking movement of the lens (); and an actuator controller () for controlling the actuator () and hence the focus and/or tracking position of the lens (), characterised in that the actuator controller () actively controls the lens position when the optical pickup () is not being used with the optical medium ().
