OPTICAL MEDIA PICKUP ANTI-RATTLE

摘要

The present invention relates to an optical media system (40) for suppressing externally induced rattle of an optical media pickup. The system (40) comprises: an optical pickup (41) for reading from and/or writing to an optical storage medium (43), the optical pickup having one or more sources of light (61), an objective lens (2), a focus and/or tracking actuator for moving the lens (2) to focus and/or track the light on the optical medium (43) and mechanical limits to limit the focus and/or tracking movement of the lens (2); and an actuator controller (58) for controlling the actuator and hence the focus and/or tracking position of the lens (2), characterised in that the actuator controller (58) actively controls the lens position when the optical pickup is not being used with the optical medium.
