摘要： A disk rotating device includes a flexible disk in which information is recordable, a turntable on which the disk is held, a spindle that rotates the disk held on the turntable, and a stabilizer that stabilizes the rotating disk. In the disk rotating device, a rotation transmitting device transmits the rotation of the spindle to the disk via the turntable, and a disk holding device holds the disk so that the disk is elastically deformable from a center of the rotation of the disk in a radial direction of the disk.
