PURPOSE:To keep weight balance in the movement of an optical pickup and to provide a vibration resistant structure against external vibration and internal vibration. CONSTITUTION:This vibration resistant structure is provided with an optical pickup 2 and a weight in a position symmetrical with the center of a turn table and is provided with a driving means 4 moving to relative position in conformity with the movement of the optical pickup 2 on the weight side. The static balance and dynamic balance of the floated optical pickup base are kept, the vibration resistance structure against the external vibrations and the internal vibrations is obtd, and the property of the optical pickup to follow up tracks is thus improved. |
