ABSTRACT:
An objective lens driving device is provided in which a resilient supporting member supporting an objective lens holder mounting an objective lens for elastic displacement in the focusing direction and in the tracking direction has a spring constant control portion for lowering one of the first-order resonant frequency in the focusing direction and the first-order resonant frequency in the tracking direction relative to the other. The spring constant control portion is of a cross-sectional shape having one of the focusing direction and the tracking direction as the long axis. The resilient supporting member is formed by plastic deformation of a starting resilient linear material having a spring constant in the focusing direction equal to the spring constant in the tracking direction. This enables a stable control operation for the objective lens.
