description PURPOSE:To attenuate vibration to be transmitted to a disk and to enhance head positioning accuracy by providing a means for attenuating vibration in a combining part between a spindle and a hub. CONSTITUTION:The spindle is fitted direct to a housing 1, and a shaft 3 of the spindle is fixed via a bearing 4 to the housing 1. Disks 6 are layered on a hub 5, and are fixed with a jig 7 and bolts 8. Then, a discoid tip of the shaft 3 of the spindle and the hub 5 are combined by a bolt 10 in common use as a vibration absorbing material 9 and a spring member. By this method, a high frequency component of the vibration to be transmitted from the spindle to the disks can be attenuated, and influence of vibration at the time of servo write is alleviated, and hence the positioning accuracy at the time of recording and reproducing is enhanced.
