Embodiment Construction

[0024] Hereinafter, a preferred embodiment of the disc clamping device according to the present invention will be described with reference to the accompanying drawings.

[0025] image 3 is an exploded perspective view of a disc holding device according to an embodiment of the present invention. Figure 4 yes image 3 Cross-sectional view of the platter holding device shown. see image 3 and Figure 4 , a disc clamping device 140 includes a clamper 141, which clamps the disc D placed on the turntable 131, and is supported by a clamper plate 147 so as to be movable. The clamper 141 is installed between the upper clamper fixer 142 and the lower clamper fixer 143 so that it can move relative to the upper clamper fixer 142, and the clamper will respond to the elastic force described below. Compression or expansion of element 146 moves. A first magnetic member 144 is installed between the upper and lower holder holders 142 and 143 , and a second magnetic member 133 is install...

Abstract

The invention provides a disc clamping apparatus including an upper clamper holder, a lower clamper holder which is combined with the upper clamper holder, a clamper which is movably installed between the upper clamper holder and the lower clamper holder and clamps a disc that is disposed on a turntable, a first magnetic member installed between the upper clamper holder and the lower clamper holder, a second magnetic member installed on the turntable to face the first magnetic member so that a magnetic force operates between the first magnetic member and the second magnetic member to clamp the disc and an elastic member disposed between the upper clamper holder and the clamper so as to provide an elastic force to push the clamper against the disc. The disc clamping apparatus clamps discs having various thicknesses. Also, a clamping force of the disc clamping apparatus is changed in proportion to the thickness of the disc, and thus a proper clamping force can be applied to the disc based on the thickness of the disc.

Description

technical field [0001] The present invention relates to a disc holding device for holding a disc, wherein the disc is a recording / reproducing medium in a disc drive. Background technique [0002] Generally, a disc drive for recording information on and reproducing information from a disc includes a disc clamping device for clamping the disc so that the disc can rotate stably. [0003] figure 1 is an exploded perspective view showing a traditional platter drive, figure 2 is a cross-sectional view of a conventional platter clamping device. [0004] Such as figure 1 As shown, a disc drive 1 includes a disc case 10 , a tray 20 , a base 30 , a disc holding device 40 and a cover 50 . The disc case 10 has upper and lower cases 11 and 12 which form a space containing the disc D. As shown in FIG. A turntable 31 for placing the disk D and a pickup 32 for picking up data recorded on the disk D are mounted on the base 30 . Such as figure 2 As shown, th...
