A bearing includes a hub to drive recording media; a sleeve to rotatably support the hub to define a hydrodynamic pressure generating space between the hub and the sleeve, the sleeve being formed with a fluid outlet through which the fluid passes at the predetermined position; a plurality of recesses to generate hydrodynamic pressure, the recesses being formed on at least one of the hub and the sleeve to be opened toward the hydrodynamic pressure generating space; and a fluid circulating member to circulate the fluid out-flowing from the fluid outlet to the hydrodynamic pressure generating space, the member being fixedly combined with the hub to slidably support the sleeve.
