Abstract
A disk driving apparatus includes a base member, a hub member, and a fluid bearing unit. The base member has a head movement region on which a head unit is to be mounted such that a head portion of the head unit can be moved along the radial direction of a recording face in a reciprocating manner while facing the recording face of a recording disk to be mounted on the hub member, and a recessed housing portion housing the fluid bearing unit such that it surrounds at least a part of a rotor unit supported by the fluid bearing unit. Furthermore, the base member has an inhibiting wall at a boundary between the head movement region and the recessed housing portion so as to prevent a lubricant fluid from migrating toward the recording disk side.
