ABSTRACT:
A tilt device for controlling the optical axis of an optical head in an optical disc playback device for optical discs such as a Laser Vision Disc and a Compact Disc in a perpendicular relation to the surface of an optical disc comprises a tilt mechanism for tilting a feed shaft disposed in the radial direction of an optical disc and having an optical pickup mounted reciprocably thereon so as to change the angle of optical axis of the optical pickup, a detector for detecting distance between the optical pickup and the optical disc and producing a detection signal, and a servo system responsive to the detection signal for controlling the tilt mechanism to maintain the distance between the optical pickup and the optical disc constant. In a preferred form, the feed shaft is fixedly secured to a base frame at its end portion nearer to the center of the optical disc and the free end of the feed shaft is moved by the tilt mechanism toward or away from the optical disc thereby to bend the feed shaft in conformity with flexion of the optical disc.
