ABSTRACT:
According to one aspect, an optical read/write device for reading and/or writing an optical disc includes a base, optical pickup head, and a driving mechanism for slidably driving the optical pickup head. The driving mechanism includes a worm gear, a motor for rotating the worm gear, and a rack disposed between the worm gear and the optical pickup head for transferring motion from the worm gear to the optical pickup head. The rack includes a fastening portion for fixing the rack to the optical pickup head, a mesh portion for engaging with the worm gear, a restricting portion connected to the mesh portion for being blocked by the gear seat when the mesh portion is pressed by the worm gear to prevent the mesh portion from disengaging from the worm gear, and a connecting portion for connecting the fastening portion with the restricting portion.
