In an optical loading apparatus, by including a main roller installed at an inlet side of an optical disc drive; a disc guide installed in the opposite direction of the main roller with an inserted disc therebetween; a disc path control member which can change disc path; a small disc stopping member formed at the drive in order to make an inserted small disc stop at a position mountable onto a spindle; and a large disc stopping member formed at the drive in order to make an inserted large disc stop at a position mountable onto a spindle, it is possible to reduce a fabrication cost by reducing the number of parts by simplifying a structure, and accordingly different-sized optical discs can be reliably loaded.
