A disc device includes the following: a traverse base 5 that can be moved between a recording/reproducing position and a standby position, on which an optical pickup 2 and a turntable 1 are mounted; a front cover 3 including a disc carrying surface 3a and an aperture 3b; a clamp base 10 that can be moved between a first position that does not overlap the disc carrying surface 3a and a second position that overlaps the aperture 3b and includes a damper 11 for clamping the disc 4 to the turntable 1; and an open/close member 9 that is movably provided at the back of the front cover 3 and can cover/uncover the aperture 3b. When the disc 4 is clamped, the clamp base 10 is moved from a standby position to the position overlapping the aperture 3b, then the open/close member 9 is moved to open the aperture 3b, and subsequently the traverse base 5 is moved from the standby position to the recording/reproducing position, thereby clamping the disc 4 with the turntable 1 and the damper 11. This disc device can facilitate the loading of the disc and protect the traverse portion.
