The present invention provides a recording medium driving apparatus comprising an enclosure having an insertion port for insertion and discharge of a recording medium; a holder holding the recording medium inserted through the insertion port; a driving section having a turntable onto which the recording medium held by the holder is mounted and a locating member for positioning the recording medium; a holder transfer mechanism for transferring the holder in a first direction approaching the driving section and in a second direction leaving the driving section; an elastic support member elastically supporting the driving section in the enclosure; and a constraining mechanism constraining transfer of the driving section; and before the holder having the recording medium inserted therein is transferred by the holder transfer mechanism in the first direction, or after beginning moving in the first direction and before a recording medium inserted in an abnormal direction or posture comes into contact with the turntable or the locating member, the constrained state of the driving section by the constraining mechanism is released. As a result, it is possible to alleviate the pressing force, produced when the holder holding a recording medium inserted in an abnormal state approaches the driving section and the recording medium in the holder comes into contact with the turntable or the locating member, under the effect of elastic supporting members supporting the driving section, thus preventing deformation or a positional shift of the turntable or deformation of, or damage to, the recording medium.
