Abstract: The invention relates to a lens mounting (11) for an electrodynamic device for recording and/or reading information in and/or from optically readable discs, which device comprises a frame with supporting means for guiding the lens mounting. The lens mounting comprises a first part (27) which cooperates with said supporting means and a second part (31) which is movable relative to said first part and which comprises the mount (32) for a lens system for focusing a radiation beam. The lens mounting (11) further comprises connecting means (33A, 33B and 35) which movably connect the first and the second part to each other. Respective opposite ends of the connecting means are embedded in the first part and the second part of the lens mounting by injection molding into a molding which is configured so that the relative position of the first and second parts are defined by the corresponding portions of one molding die.

Abstract: Apparatus for writing and/or reading information in an information surface of a rotating disc by means of a radiation spot (5) includes a one-piece injection-moulded or die-cast frame (11) and a motor unit (57) with a motor shaft (43) which carries a turntable (45) and which is journalled in the frame (11). The device further comprises an optical system with a movable lens system (17), and a lens-system driving device (13) with a movable lens carrier (15).
