Abstract

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).

Description

technical field [0001] The present invention relates to an optical disc device for playing and recording an optical disc on which information is recorded, and more particularly to an optical disc device having an adjustment unit for adjusting the inclination and height of a turntable for positioning and placing an optical disc, and for supporting and picking up optical discs. Adjust the inclination of the guide shaft of the optical pick-up. Background technique [0002] As a conventional optical disk device, there is a device in which a basic unit chassis of a stator substrate of a spindle motor (spindle motor) is used for the purpose of realizing high-precision tilt (skew) adjustment with a simple structure. (base unit chassis), a radial (radial) adjustment unit and a tangential (tangential) adjustment unit are set. [0003] The tilt adjustment in this conventional device (for example, refer to Patent Document 1) is performed as follows. First, the optical pickup is moved...
