摘要： A medium attaching device for attaching and holding a disk to and releasing the disk from a turntable of a disk device. A plurality of holding/releasing devices are arranged radially around a center hub of the turntable. Each holding/releasing device includes a clamp member of generally crescent form having a holding section and a releasing section located on opposite sides with respect to a swivel center. When the disk is transferred to a predetermined position of the disk device, the clamp members are swiveled around the swivel center to either attach and hold the disk to the turntable, or raise the disk to a position above the turntable and hence to release the disk therefrom.
