ABSTRACT:
According to one aspect, an optical recording and/or reproducing device for reading and/or writing an optical disc includes a base, optical pickup head, and a moving mechanism for slidably moving the optical pickup head. The moving 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, an engaging portion for engaging with the worm gear, a restricting portion connected to the engaging portion for preventing the engaging portion from running out of the worm gear, and a connecting portion for connecting the fastening portion with the restricting portion.
