摘要： A disk device configured in such a manner that, in addition to tilt adjustment, the adjustment of the distance between a disk and an optical pickup can be easily performed. The disk device is provided with a stepping motor (23) for moving the optical pickup (5), a base chassis (2) to which a spindle motor (3) for rotating a turntable on which a disk (1) is affixed is mounted so as to be adjustable in position, a guide shaft (6) provided to the base chassis (2) so as to extend in the radial direction of the disk and guiding the movement of the optical pickup (5) by being in contact with a portion of the optical pickup (5), a sub guide shaft (7) provided to the base chassis (2) and guiding the movement of the optical pickup (5), a tilt adjusting section (300) for adjusting the relative distance between the sub guide shaft (7) and the base chassis (2), and a turntable adjusting section (200) for adjusting the radial angle, the tangential angle, and the height of the spindle motor (3) relative to the base chassis (2).

摘要： A disk device, wherein a disk clamp unit is further thinned. 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 (401G) and attracted by the magnet (302).
