Abstract
A stabilizing part applying aerodynamic force to the recording medium so as to control disk axial runout of the recording disk and stabilize it; the stabilizing part includes a main stabilizing member for a recording/reproduction position with the recording/reproduction unit and an auxiliary stabilizing member for positions other than the recording/reproduction position; the auxiliary stabilizing member inclines the disk surface of the recording disk from a plane perpendicular to the rotational axis of the recording disk, and said main stabilizing member generates a positive or negative pressure in the recording disk rotation direction to cancel out inclination in the recording/reproduction surface of the recording disk.
