Abstract
According to one aspect, an optical read/write device for reading and/or writing an optical disk includes 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, a spring placed between the fastening portion and the engaging portion for pressing the engaging portion to engage with the worm gear, and a connecting portion. The connecting portion is configured for connecting the fastening portion and the engaging portion and preventing the engaging portion from disengaging from the worm gear.
