Abstract
In an optical disk apparatus in accordance with the present invention, a tilt chassis (3, 201) to which a main shaft (6) and a sub shaft (7), being parallel with each other and serving to guide the movement direction of an optical pickup (50), are secured is disposed rotatably with respect to a traverse chassis (4) to which a spindle motor (2) is secured, and the tilt chassis (3, 201) is configured so as to be tilt-adjustable with respect to the traverse chassis (4) by tilt adjustment means having two tilt adjustment portions (30, 31), whereby tilt adjustment work for adjusting the movement face of the optical pickup so as to be parallel with the recording face of an optical disk is made easy.

An optical disk apparatus comprising:
- a turntable on which an optical disk is mounted;
- a spindle motor for driving said turntable;
- a traverse chassis to which said spindle motor is secured;
- an optical pickup, moving in the radial direction of said optical disk, for reading information written on said optical disk or writing information on said optical disk;
- a tilt chassis provided with a main shaft and a sub shaft, being parallel with each other, for guiding the movement direction of said optical pickup;
- and
- tilt adjustment means, having an elastic member so as to absorb vibration between said tilt chassis and said traverse chassis, for tilt-adjusting said tilt chassis with respect to said traverse chassis, wherein said tilt adjustment means comprises two tilt adjustment portions, said tilt chassis is engaged with said traverse chassis so as to be contactingly movable at one adjustment support portion, said adjustment support portion is disposed in the vicinity of the end of said main shaft on the inner circumferential side of the optical disk, one of said tilt adjustment portions is disposed in the vicinity of the end of said main shaft on the outer circumferential side of the optical disk, and the other tilt adjustment portion is disposed on the side of said sub shaft.
An optical disk apparatus comprising:
- a turntable on which an optical disk is mounted,
