According to one embodiment, an optical disc apparatus according to an embodiment of the present invention has a loading arm. The loading arm has two projections provided, respectively, at a distal end and at a position prescribed in accordance with a difference in diameter between optical discs. The loading arm can rotate in a direction in which an optical disc is inserted. It rotates when the optical disc contacts at least the projection provided at the distal end. It positions the optical disc when it is rotated through an angle prescribed in accordance with the difference in diameter between the optical discs, by using the two projections spaced apart by a distance prescribed in accordance with the difference in diameter between the optical discs. When the loading arm is rotated in the opposite direction, the optical disc is ejected from the optical disc apparatus.
