A disc player comprises a disc holding/separating mechanism which holds the plurality of discs concentrically and which separates the selected disc from the remaining discs; a turntable; a pickup; a playback base which supports the turntable and which moves toward and away from the disc holding/separating mechanism; a clamper which secures the selected disc to the turntable; a damper arm which supports the clamper and which moves toward and away from the disc holding/separating mechanism; a translating mechanism which supports the playback base and the clamper arm and which moves toward and away from the disc holding/separating mechanism; and a control mechanism which controls motions of the playback base, the clamper arm and the translating mechanism in such a way that, when the selected disc is put on the turntable by the disc holding/separating mechanism, the turntable is placed at a first position, which is located on a central axis of the plurality of discs held by the disc holding/separating mechanism, and when the pickup reads out data from the selected disc, the turntable is placed at a second position, which is located at a predetermined distance from the first position.
