Abstract: A slot-loading optical drive structure is proposed. It includes a base with a gearing for driving a sliding body to move a sliding plate. The sliding plate has a positioning slot for guiding a push rod to push an optical disc into the optical drive. Thereby, a positioning rod can presses one side of the optical disc, the push rod can presses the back end of the optical disc, and a rod connection means can presses the front end of the optical disc. Hence the optical disc can be positioned at a fixed location to make the central hole of the optical disc correctly aligned to the center of the turntable of the traverse inside the optical drive. Thus, the optical disc can be settled on the turntable and the optical drive can rotate the optical disc for data access.
