To provide a loading device in a magnetooptical disc recording apparatus having a sufficiently wide space for the magnetooptical disc between an elevation mechanism and a driving unit without positioning a holder lever constituting the elevation mechanism between a clamper and the driving unit, and a space for avoiding contact between the holder lever and the magnetooptical disc, an elevation mechanism and a plurality of holder levers are disposed removably in a radially outward direction to be substantially flush with the clamper and adapted to give a vertical motion and a opening and closing operation in a radial direction to the holder lever in cooperation with the rotation of the clamper base. When the magnetooptical disc is loaded or unloaded, the clamper is moved upwardly by engagement with the holder lever to maintain said sufficient space. When the magnetooptical disc is rotated, the holder levers are separated away from the magnetooptical disc through the guide cams while being released outwardly to avoid said contact.
