摘要： A optical pickup system for use in a disk drive includes a stepping motor, a lead screw supported by a bracket and coupled to the stepping motor, in which the lead screw has spiral grooves formed on an outer periphery of the lead screw and engaged to a slider to move an optical pickup head in a radial direction of a disk, a plurality of guide shafts, installed to a main base in parallel with the lead screw, for guiding the optical pickup head in the radial direction of the disk, and a positioning mechanism for supporting the bracket which is installed to the main base to move in any direction to automatically maintain a position of the lead screw to the slider, thereby minimizing a load applied to the stepping motor.

摘要： An optical pickup transferring apparatus including a slider having a base, a floating portion elastically coupled to the base, the floating portion having on one side thereof at least one protuberance inserted into the external thread of a lead screw, and an elastic element located on the top of the base and the floating portion. The elastic element includes a first elastic portion to push the floating portion toward the lead screw so that the protuberance is inserted into the external thread, and a second elastic portion to push the floating portion toward the screw groove to thereby prevent the protuberance from escaping from the external thread when the floating portion is transformed elastically.
