Abstract: A transmission apparatus for use in a stack of data library units, the stack comprising a lower data library unit and an upper data library unit, each data library unit of the stack comprising a plurality of upright frames, the transmission apparatus comprising a tray for transporting a tape cartridge; a plurality of positioning pinions rotatably attached to the tray; a plurality of racks each disposed on each of the plurality of upright frames and configured to be engaged by the corresponding plurality of positioning pinions for vertical positioning of the tray within each data library unit; a plurality of partial racks each comprising an upper tooth and a lower tooth disposed adjacent the plurality of racks at each of the plurality of upright frames, the upper tooth being disposed adjacent a lower end of the frame of the upper data library unit and the lower tooth being disposed adjacent an upper end of the frame of the lower data library unit; a plurality of cross-over pinions each rotatably attached to th

Abstract: Disclosed is an apparatus for reading information recorded on the track of a data carrier (1). The apparatus comprises a rotating device (2) for supporting and rotating the data carrier (1) around an axis of rotation (3). The rotating device (2) comprises a turntable (21) and a motor (23) for rotating the turntable (21). The apparatus according to the invention is able to suppress a wobble introduced by the data carrier (1) when rotated. This is done by a flexible part (24) in the rotating device (2). In an embodiment the supporting surface of the turntable (21) comprises the flexible part (24). This allows the data carrier (1) to tilt in radial and tangential direction. The centrifugal forces, which are present when rotation the data carrier (1), are able to level the data carrier (1), thus reducing the wobble.

Abstract: The invention relates to an apparatus for reading or writing information on a circular information carrier (D) having a periphery, said apparatus comprising a turntable (501) for clamping and rotating said information carrier (D), said information carrier (D) having an initial tilt from the radial direction of the turntable. The apparatus comprises additional means for applying an end load at the periphery of said information carrier, so as to apply a tilt of known value to said information carrier with respect to the radial direction of the turntable (501), said known value being larger than said initial tilt. The clamping surface of the turntable (501) may be tilted appropriately.
