の駆動装置。[Claim for Utility Model Registration] A yoke made of iron-based material is rotatably attached around a fixed shaft via a bearing, a hub made of aluminum-based material is fixed around the yoke, and a disk-shaped yoke is fixed around the yoke. In a drive device for a disk-shaped record carrier to which a record carrier is fixed, the hub has a two-layer structure consisting of an inner member fixed around the yoke and an outer member to which the disk-shaped record carrier is fixed, An annular gap is formed in the longitudinal center of one of the inner members and the inner member and the outer member, and annular gaps that partially overlap with the above gaps are formed in both longitudinal ends of the other. A drive device for a disk-shaped record carrier, characterized in that:
