摘要： A device in which an offset is added to a focusing error signal to control an objective lens and thereby reduce the generation of cross-talk when a beam spot that is converged on an optical disk crosses over a wall of a groove of a track of the disk. By adding the offset to the focusing error signal, the objective lens is moved out of focus with the disk. Thus, the shape of a beam spot formed on a photo sensor is changed from a circle to an ellipse. A condenser lens provided for forming the beam spot is moved along the optical axis thereof in such a manner that an output of a recorded signal of the disk is at a maximum value. As a result, the objective lens is brought into focus on the disk. Thereafter, the objective lens is focused on the disk in accordance with the focusing error signal to which the offset is added, while maintaining the beam spot in the shape of an ellipse.

摘要： An apparatus and method for inspecting a beam splitter which is to be used in splitting a laser beam. The apparatus includes laser beam sources (including laser diodes and collimator lenses) for projecting a plurality of images through the beam splitter being inspected and onto a single photo detector. Based on the relative positions of the images on the photo detector, an accuracy characteristic of the beam splitter to be inspected can be determined. Each of the light beams emitted from the beam sources are transmitted through a condenser lens and through a pinhole provided in a diaphragm plate having a ground glass plate on an incident side. The pinhole provides a point source which is converted into a parallel beam by a lens. The beams are then made incident on the beam splitter to be inspected, are transmitted and reflected, and are emitted onto the photo detector in a relationship related to the accuracy characteristic of the splitter. The beams form images on a monitor connected to the photo detector.

The optical information recording/reproducing apparatus includes a laser light source, an objective optical system for converging the light beam from the laser light source, a guide rail mechanism for moving the objective optical system, a beam splitter mounted in an optical path of the light beam parallel to the transfer direction and photodetectors for detecting the light beam split by the beam splitter. The method of adjusting the beam splitter includes supporting a supplementary laser source for emitting a laser beam on the guide rail mechanism so that the laser beam of the supplementary laser source is incident onto the beam splitter along the optical path. The method further includes adjusting the beam splitter, while observing the split laser beam from the beam splitter at plural points where the photodetectors are to be mounted.
