PROBLEM TO BE SOLVED: To reduce vibration within a specific frequency range when an optical disk drive body is vibrated by mounting a vibration absorber with appropriate stiffness and an attenuation coefficient to the optical disk drive body. SOLUTION: A vibration-absorbing device adds one set of or a number of vibration absorbers to a damping elastic body 4 in an optical disk device body 1. In this case, one set of vibration absorbers are composed of one object 2 with mass and inertia moment effect and one or several elastic bodes 3 with appropriate stiffness and attenuation coefficients. The elastic bodies 3 can be composed of a spring, damping rubber, and the like. By mounting this sort of vibration absorbor to the optical disk drive body 1, the vibration of the optical disk drive body 1 can be absorbed by the operation of the elastic bodies 3. Also, when the optical disk drive is formed by the combination of disk mount structure and the optical disk drive body 1, the vibration absorbor can be mounted to the combined body.
