System for actively controlling the lense of an optical pickup when not in operation

An optical media system comprising:

• an optical pickup for reading from and/or writing to an optical storage medium, the optical pickup having wall portions defining a cavity having an opening, one or more sources of light, and an objective lens disposed within the cavity, the optical pickup being movable between a park position when not in operation and an operating position when in operation;
• 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, the actuator controller configured to induce a magnetic field interacting with the optical pickup to actively control the lens position within the cavity via the magnetic field when the optical pickup is in the park position;
• in which the optical pickup is moved to the park position away from the optical medium when not being used with such an optical medium.
