Abstract
A device for inscribing and/or reading a magneto-optical disc (7), including a frame (1) carrying a turntable (5) which is rotatable about an axis of rotation (11), a slide (17) carrying an optical unit (19) a rectilinear guide (15) for the slide arranged on the frame, and a slide-drive unit (25). A sub-frame (3) is secured to the frame so as to be movable, and a further slide (57) to which, viewed along the axis of rotation, a magnetic unit (59) is secured at a location opposite to and spaced from the optical unit. The sub-frame carries a further rectilinear guide (55) for the further slide, which further rectilinear guide extends parallel to the rectilinear guide for the first-mentioned slide at least during operation.
