摘要： An objective lens driving apparatus for an optical pickup includes a blade on which an objective lens can be mounted, a plurality of elastic support members supporting the blade and capable of elastically moving with respect to the blade, and a servo mechanism driving the blade up and down, left and right, and in a rotational direction. The elastic support members are grouped into pairs arranged to face each other with respect to a center of rotation of the blade, and distances between the elastic support members in the respective pairs are substantially identical. By lessening the difference in the amount of deformation between the elastic support members supporting the blade during tilt control, the elastic support members are less likely to move in undesired directions when vibration is applied.

摘要： An optical head for near-field recording and reproduction, and a method of manufacturing the optical head. A vertical cavity surface emitting laser (VCSEL) and a photodetector are formed on a slider, and a lens layer, an optical path control layer and/or a coil member are directly formed over the VCSEL and the photodetector by thin film deposition. Combining the optical system for information recording and reproduction with the slider reduces the size of the optical head compared with an optical head adopting a slider and a large optical system which are separated from each other. As a result, dynamic characteristics of the optical head improve, thereby reducing the time required for searching for a target track. Thus, the optical head is suitable for a micro information recording and reproducing system.
