Embodiment Construction

[0019] figure 1 A cross-sectional view of a first embodiment of an information carrier comprising a disc 1 is schematically shown. The central part 1a of the disc 1 is provided with a substantially cylindrical hole 5 concealedly housing a movable positioning element 3 . The positioning element 3 of said first embodiment is a movable ball 3 in the transverse disc direction T with respect to the information bearing disc part 1b. figure 1 A first transverse position of the sphere 3 is shown.

[0020] FIG. 3 shows the application of the information carrier of the first embodiment in combination with a turntable 4 . The turntable 4 is configured to cooperate with the positioning ball 3 of the information carrier disc 1 . More specifically, the turntable 4 comprises corresponding positioning means, which are substantially conical positioning holes 7 provided in the disc bearing surface 9 of the turntable 4 . Such as Figure 3A and 3B As shown, the disk 1 is moved in a substant...

Abstract

Information carrier comprising a disc (1) provided with positioning means (3) arranged to cooperate with a disc drive turntable (4) for positioning the disc on the turntable. The positioning means are movable at least in a transversal disc direction (T) relative to the disc.

Description

Background technique [0001] The invention relates to an information carrier comprising a disc provided with positioning means configured to cooperate with a disc drive turntable for positioning the disc on the turntable. [0002] The invention further relates to a turntable. [0003] Such information carriers and turntables are known from practical use. The information carrier may comprise, for example, a compact disc, a small form factor disc (SFF disc) or the like. The positioning device of the known information carrier comprises a central disk hole. Known turntables include fixed positioning axes. In use, the disc is positioned on the turntable as the disc is positioned on the turntable such that the turntable shaft extends through the central disc aperture. [0004] A problem with known information carriers and known turntables is that when loading a disk into a corresponding disk playback and / or writing device, the disk has to be moved in an axial direction on the axi...
