The present disclosure is directed to a disk-positioning device for use in an optical disk device that can receive and position optical disks of different sizes. Embodiments of the device comprise a substrate, a locking rod having a locking extension, a right positioning plate, a left positioning plate, a trigger arm and a sliding element. A gear rack and a spur gear are integrally formed with the left positioning plate and the right positioning plate respectively, and the spur gear and gear rack are in mesh when the optical disk device is in use. Furthermore, two locking notches are integrally formed with the right positioning plate. When the disk having a first size is loaded, the locking pin of the locking rod disengages from one of the two locking notches. When a disk having a second size is loaded, the locking rod maintains its lock with the right positioning plate.
