The disk device is provided with a spindle motor (300) for positioning and rotating a disk, an alignment ring (301) fixed to the rotating shaft of the spindle motor, and a clamp section (400) for mounting the disk on the spindle motor (300). The alignment ring (301) is provided with a projection section (301C) formed around the rotating shaft of the spindle motor (300), and a magnet (302) provided around the rotating shaft with a space provided between the magnet (302) and the projection section (301C). The clamp section (400) is provided with a center member (401) having formed therein a recessed space (401G) in which the projection section (301C) is fitted, and also with a member (402) to be attracted which is attracted by the magnet (302). The clamp section (400) is adapted in such a manner that the disk is mounted on the spindle motor (300) when the projection section (301C) is fitted in the recessed space (401 G) and attracted by the magnet (302).</p>
