ABSTRACT:
An apparatus for recording and/or reading information on an optically readable disc (3) includes a carrier (6) which can be driven along a first axis (4) in order to move a lens system (1) which is arranged on the carrier relative to the disc. The lens system is also driven along said first axis by drive means (33) which act directly, i.e. not via the supporting means (21, 22), in order to minimize the load exerted on the supporting means.
