Herein disclosed is a disc drive apparatus for driving an optical disc having a central portion formed with a central hole, comprising: a frame member, a disc retaining member rotatably supported by the frame member, a cam member supported by the disc retaining member and rockable with respect to the disc retaining member, a plurality of disc holding members each supported by the disc retaining member and operatively coupled with the cam member, each of the disc holding members being movable with respect to the disc retaining member to assume two different operation positions including a disc holding position in which each of the disc holding members is held in contact with the central portion of the optical disc, and a disc releasing position in which each of the disc holding members is held out of contact with the central portion of the optical disc, and a resilient member intervening between the disc retaining member and each of the disc holding members to have each of the disc holding members resiliently urged to assume the disc holding position.
