Abstract
An apparatus comprises a moveable arm for positioning an optical transducer adjacent to a storage medium, a stationary light source, and a moveable mirror mounted at a pivot axis of the arm for reflecting light from the light source to the optical transducer. An actuator can be provided for rotating the moveable mirror through an angle of about one half of an angle of rotation of the moveable arm.
