ABSTRACT:
An optical disk apparatus includes a turntable with a bearing surface, and a spindle motor for rotating the turntable. The spindle shaft has a cylindrical first shaft having an upper end flush with the bearing surface, and a second shaft having an upper end portion and arranged in the first shaft to be slidable between an engaging position in which the upper end portion projects from the upper end of the first shaft to engage a center hole of an optical disk placed on the bearing surface and a depressed position in which the upper end portion is recessed from the upper end of the first shaft to be disengaged from the optical disk. The second shaft is moved by a spindle moving mechanism from the first position to the second position when the optical disk is to be loaded on and unloaded from the turntable.
