Abstract: A rotating device is a device in which a sleeve of a rotor surrounds a shaft of a fixed body, a lubricant intervening between the shaft and the sleeve. A gap between the shaft and the sleeve includes two dynamic pressure generation portions spaced apart from each other in an axial direction. The rotor and the fixed body are arranged such that a center of gravity of the rotor having a plurality of magnetic recording disks mounted thereon is positioned between the two dynamic pressure generation portions.
