Abstract
A magnet disposed on the top face of an extended part of a bearing holding member has a semicircle shape as the maximum shaper and is disposed in the same direction as the movement direction of a disk dray in the circumferential direction. By the pulling force in the axial direction between the magnet and a rotor holder, the shaft tilts at an angle different from the gravity direction or a direction opposite to the gravity direction.
