The invention provides an optical information recording and reproducing apparatus which can record and/or reproduce an information on both a holographic storage disc and a conventional optical storage disc, can improve a usability, and can achieve a downsizing and a low cost. The optical information recording and reproducing apparatus can record and reproduce an information on both a holographic storage disc and an optical storage disc recording and/or reproducing the information at a time of a high speed turning, by an optical pickup, and is provided with a stepping motor driving the holographic storage disc, and a direct-current motor driving the optical storage disc, and a rotating shaft of the stepping motor and a rotating shaft of the direct-current motor are constituted by a common rotating shaft.
