ABSTRACT:
A disk drive system according to the present invention comprises a spindle in a drive unit. The spindle is formed, at its free end, so that it has a flat portion. A magnetic disk which is adapted to be rotated by the spindle is provided having a center hub in its central portion. An opening in the shape of a right-angled isosceles triangle is formed in the center of the center hub. The free end of the spindle can be inserted into the opening, with some play therebetween, only when it is located within a predetermined range of the phase angle of rotation relative to the magnetic disk. The opening has, on its base, a first contact point adapted to abut against one side edge of the flat portion, located on the front side, when the free end of the spindle is inserted into the opening. The opening also has, on the two remaining sides thereof, second and third contact points adapted to engage some other portions of the outer peripheral surface of the free end of the spindle.
