摘要： The invention provides an optical head device in which the influence of mechanical vibration generated at resonance frequencies of high orders (second and higher orders) can be eliminated and an optical recording/reproducing apparatus utilizing the same. Sidewalls are formed from both ends of a sidewall constituting the top side of a trapezoidal contour of a lens holder portion, the sidewalls extending in the form of a fan to define a predetermined angle between them. A damping system includes a weight in the form of a metal thin plate and a visco-elastic adhesive for bonding the weight to the sidewalls. The visco-elastic adhesive transfers vibration of the lens holder in the direction of an optical axis of an objective lens to the weight and has a viscous damping property which damps vibration of the weight in the direction of the optical axis.
