Abstract
Device for reading an optical disc (5) includes a turntable (17) which is rotatable about an axis of rotation (19), and a slide (11) supported directly in the frame and which carries an objective (9) having an optical axis (9a). A slide-supporting arrangement is constructed in such a way that it allows both the displacement of the slide in a radial direction and a pivotal movement of the slide about a pivotal axis (13) which is stationary relative to the frame. A slide-drive arrangement (31, 33) radially moves the objective, and a drive unit (25, 27) with a control element (29) tilts the slide.
