A vibration damping means ( 30 ) for an optical reproducing/recording apparatus ( 100 ) includes a first damper ( 4 ), and a second damper ( 5 ) received in the first damper. The first damper has a damp coefficient adapted to absorb vibrations generated due to the spindle motor rotating. The first damper includes first and second engaging portions ( 41, 42 ) at opposite ends thereof, and a deformable portion ( 43 ) between the first and second engaging portions. A flange ( 45 ) extends from an interior surface of the deformable portion. The second damper defines a groove ( 52 ) engagingly receiving the flange of the first damper. If the apparatus sustains an impact or shock, the first and second dampers are deformed together. The overall damp coefficient of each damping means equals the sum of the damp coefficients of the first and second dampers. This larger damp coefficient enables the damping means to satisfactorily absorb the large intensity vibration.
