Abstract: The present invention relates to a CD changer of the “carousel type”, in which three or five optical recording media, referred to below as disk, are arranged on a rotatable disk holder, the carousel. It has a drawer (2) which can be moved between a retracted and an extended position by a drawer movement mechanism (8). The object of the invention is to propose a solution which improves the functionality of the CD changer. It is proposed in the invention that the drawer has a stop (15, 25) which, in the extended position, bears against a pin (11, 21) of the drawer movement mechanism (8), and which, when force acts on the drawer (2), exerts on the drawer movement mechanism a force which is directed in the radial direction of said mechanism.

Abstract: In order to provide a protective cover for an objective of an optical head, which can be used both when the optical head is installed and during its production and transport and, in addition, is also suitable for recording and reproducing apparatus which, during the operation of the apparatus, is able to provide only a small spacing between the optical head and the optical recording medium, a protective cover for an objective of an optical head is proposed which can be moved between a position covering the objective and a position exposing the objective. The protective cover can be locked both in the position covering the objective of the optical head and in the position exposing the objective, so that the protective cover can be used not only when the optical head is installed but also during its production and transport.

Abstract: Reproduction and/or recording device for optical recording media having a unit for adjusting the inclination of a bearing, is disclosed. The device includes a unit for adjusting the inclination of a bearing of a laser disk scanning apparatus, which has a board to which the bearing is fastened. The inclination of the bearing can be set with regard to the board by setting units, which alters the distance between the board and the bearing, the selling units each having at least one elastic element, is known. In order to improve the device to the extent that its individual components are inexpensive to produce and the adjustment can be carried out rapidly and in a simple manner, it is provided that the board has at least two elastic lugs, which are connected to the bearing. The inclinations of the lugs can be set with regard to the board by setting units, which act on the lugs.

Abstract: The invention relates to a drive system for a scanning device of an information recording or reproduction device, with a carriage coupled to a toothed rack, a gear wheel mechanism driving the toothed rack and a gear housing. It achieves the object of designing a drive system of this type alternatively and in such a way that it ensures a high speed and positioning accuracy of the carriage. For this purpose, the gear wheel mechanism is secured on a supporting element and the gear housing, the gear housing consisting of a dimensionally stable material and being pivotable with the gear wheel mechanism about a spindle which is arranged perpendicularly with respect to the toothed rack.
