| description | An example rotating device is a disk drive device that includes a base, a hub on which a recording disk is to be mounted and which rotates relative to the base, and a fluid dynamic bearing unit that allows the hub to rotate relative to the base. The fluid dynamic bearing unit includes a shaft that performs relative rotation and a cylindrical member that encircles the shaft, the cylindrical member includes a thrust dynamic pressure generating groove which is provided in one end face of the cylindrical member and which generates thrust dynamic pressure, and the thrust dynamic pressure generating groove includes a cut-and-machined face. |
