PROBLEM TO BE SOLVED: To provide a small-sized disk drive device which is provided with a small-sized buffering device that has nonlinear spring characteristics and reliably absorbs and attenuates high-frequency vibration. SOLUTION: Each pair of right and left, and upper and lower buffering devices 1, 1 are respectively provided with paired elastic bodies 2, 2 holding the main body of the device 11A. Each elastic body 2 is made by laminating four plate springs 2A to 2D the lengths on the free end sides 2b of which are different from each other and supported in a cantilever state on the both ends 3a of a fixed plate 3 while registering the fixed end side 2a. The plate springs 2A to 2D each made of carbon fiber hold both the side faces 11a of the body 11A of the device each through a spring acceptor 16A successively in the order that starts from the free end side of the plate spring 2A, the longest one among 2A to 2D. By this, each small-sized buffering device 1 reliably absorbs attenuates both external high-frequency and low-frequency vibration from which the main body 11A of the device suffers. |
