ABSTRACT:
In an optical disk apparatus applicable to super thin-sizing thereof, and further a sliding drive mechanism for an optical pickup, having a tilt adjustment mechanism, being suitable to such the optical disk apparatus, the sliding drive mechanism for an optical pickup slides the optical pickup330in the radial direction of an optical disk, wherein the optical pickup is attached to be movable on a pair of main and counter sliding shafts331and332,being disposed in parallel with, and in neighboring to the main sliding shaft is disposed a lead screw336,which is rotationally driven by a stepping motor337,in parallel, while being engaged with a rack335formed in a part of the optical pickup. Also, an end of the main sliding shaft, both ends of the counter sliding shaft, and an end of the lead screw are disposed and fixed onto a chassis being formed in one body therewith, and further the other end of the main sliding shaft and the other end of the lead screw are positioned, in one body thereof, by means of a connection member341,while the connection member is adjustable on the position thereof by means of an adjusting screw342to the chassis, thereby building up a tilt adjusting mechanism for the optical pickup.
