US 2004/0071073 A1 · Optical disk device

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.
