摘要： The present invention provides an object lens actuator in which a tilt of an object lens due to a change of an ambient temperature is inhibited even when a metal member is attached to a resin based securing part. It is desirable to improve quality of writing and playing in a disc drive using the object lens actuator. This is achieved by coupling a metal member having a flat portion and bent portions to a securing part near top ends of the bent portions. The flat portion has a normal in the focusing direction. The bent portions extend in the focusing direction from the respective ends of the flat portion in the tracking direction. The securing part has an opening therethrough in the focusing direction, and in the opening, the metal member and the securing part may be coupled between each outermost two support members in the focusing direction.

摘要： An object lens actuator can improve workability and operate with high reliability by prevention of damage to the object lens actuator and a disc and sticking of a moving part caused by an excessive movement of the moving part. In a disc drive employing the object lens actuation, stable writing/reading operation is implemented by always keeping a focal point of an object lens at a predetermined track of a recording surface of the disc even when being under the action of external perturbations such as a vertical deviation or a radial deviation of the disc, resulting in improved reliability. A solder-flux adhesion prevention gadget is provided between a substrate and a stopper receiving face, which may include a stepped stage, a partition protruding from the surface of the lens holder, or alternatively a combination of them arranged in order in the range.
