Title:
DISK DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/047808
Kind Code:
A1
Abstract:
A disk device having a thinned tilt adjustment section. A tilt adjustment member
(404) of the tilt adjustment section (400) moves an optical pickup drive section
(307) along a guide surface (401a). This adjusts an optical axis (303c) of a light
beam (303b), which is applied from an optical pickup (303), to be vertical to a
disk (200). Because the tilt adjustment member (401) moves in the direction
tilted relative to the guide surface (401a) and vertical to the optical pickup
drive section (307), the amount of movement of the tilt adjustment member (404)
can be made less than a required tilt adjustment amount of the optical pickup drive
section (307), and this enables the tilt adjustment section (400) to be thinned.
The forward end of the optical pickup drive section (307) is urged by an urging
member (405) so as to be in contact with the tilt adjustment member (404) and guide
surface (401a), so that the forward end of the optical pickup drive section (307)
is adjusted without play in the direction of approaching to and separating from
the disk (200).
