摘要： A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting member 404 of a tilt adjusting portion 400 moves an optical pickup driving portion 307 along a guide face 401a to adjust a light beam 303b emitted from an optical pickup 303 such that an optical axis 303c is set perpendicularly to a disc 200. Since the tilt adjusting member 404 is moved in a direction oblique to the guide face 401a and a direction perpendicular to the optical pickup driving portion 307, an amount of movement of the tilt adjusting member 404 can be reduced smaller than a necessary amount of tilt adjustment of the optical pickup driving portion 307 and also a slimming down of the tilt adjusting portion 400 can be achieved. In this case, since a top end portion of the optical pickup driving portion 307 is energized by an energizing member 405 to come into contact with the tilt adjusting member 404 and the guide face 401, this top end portion of the optical pickup driving portion 307 can be adjusted to come close to and go away from the disc 200 without wobbling and rattling.

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).

摘要： A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting portion 400, 500, or 600 is provided to adjust a light beam 303b emitted from an optical pickup 303 such that an optical axis 303c is set perpendicularly to a disc 200 loaded on a disc turning portion 302. As the tilt adjusting portion 400, 500, or 600, a turntable adjusting portion 600 for adjusting a tilt of the disc loading face of the disc turning portion 302, and an optical pickup adjusting portion 400 or 500 for adjusting a position of a frame 307 that holds an optical pickup driving portion 305 are provided. Therefore, a margin of adjustment in the adjusting portion can be reduced, the tilt adjusting portion 400, 500, 600 can be reduced in size, and a slimming down of a disc device 100 can be achieved.
