ABSTRACT:
An apparatus for supporting an optical system such as an objective lens in an optical recording and/or reproducing apparatus movably in a focusing direction and/or tracking direction including an optical system holding member, a stationary member which is provided on a carriage moving in a radial direction of an optical record disk, leaf springs having one ends connected to the optical system holding member and the other ends secured to the stationary member and being arranged in parallel with each other such that the holding member can be moved in a given direction with respect to the optical record disk, and a damping member arranged between the leaf springs for providing a damping function. The damping member is formed by injecting a fluidizable damping material into a space formed between the leaf springs and retaining the thus injected fluidizable damping material therein by a surface tension. The injected damping material may be cured to form the damping member, if necessary.
