Abstract
An air flow generated during disk rotation is rectified to suppress disk vibrations and prevent the qualities of recorded and reproduced signals from being degraded. Notches 24 and 26 are formed on top edges of right and left side walls 22 and 22 of a frame 10. Opposite ends of a clamp holder 28 along its long side direction are fixedly mounted on the notches 24 and 26. Rectifiers of repetitive structures 32 and 34 having a wave shape as viewed in plan are formed on the clamper holder 28 on the plate portions 28a and 28b on both sides of a clamper 30 and at edges on the output side of an air flow generated during disk rotation.
