| 摘要 |
<p>The invention relates to optical-disk apparatus for playing back and/or recording information on rotary optical discs (7), which apparatus comprises a clamping device which clamps an optical disc on a spindle (14). The clamping device comprises a disc loader (21) which moves with clearance in a support (2) which moves between the rest position and an operating position, which disc loader clamps the disc magnetically onto the spindle by means of permanent-magnetic means. To prevent the disc loader rattling or taking up an oblique position in the support when the support is not in its operating position, the permanent-magnetic means comprise means (35A, B) which exert a magnetic force which acts between the support and the disc loader so that the disc loader is clamped against the support when the latter is not in the operating position.</p> |
