<P>PROBLEM TO BE SOLVED: To simplify the work for exchanging a simulative member, and to improve working efficiency in the work for adjusting an optical pickup, in an apparatus for adjusting the optical pickup, utilized in adjusting the tilt of an objective lens. <P>SOLUTION: The apparatus for adjusting the optical pickup is provided with a simulative member supporting device 30 composed of a holding plate 32 and a plate supporting table 33. The holding plate 32 is formed on a disk, in which a plurality of through holes are provided along the circumferential direction of the disk, and in which the plurality of simulative members 31, each having a different optical characteristic, are attached to the plurality of through holes, respectively. The holding plate 32 is rotatably supported by the plate supporting table 33. The simulative member 31 having the desired optical characteristic is placed on the optical axis of a laser light emitted from an automatic collimator 50 and of the laser light transmitted through the objective lens 14, by rotating the holding plate 32. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
