Patent ID: 7367036

Claim:
A recording/reproduction apparatus comprising: a driving part rotating a flexible recording disk about a rotational axis thereof; a stabilizing part applying aerodynamic force to the recording disk so as to control disk axial runout of the recording disk and stabilize it; and a recording/reproduction unit carrying out recording/reproduction of information to/from the recording disk by scanning it, wherein: said stabilizing part comprises a main stabilizing member for controlling disk axial runout at a recording/reproduction position with the recording/reproduction unit; and an auxiliary stabilizing member for stabilizing the disk surface at positions other than the recording/reproduction position; said auxiliary stabilizing member is applied for the recording disk in such a manner as to incline the disk surface of the recording disk from a plane perpendicular to the rotational axis of the recording disk, and said main stabilizing member is applied for the recording disk in such a manner that positive or negative pressure is generated in the recording disk rotation direction, so as to cancel the inclination in the recording/reproduction surface of the recording disk.
