Using a compound optical element with three polarized holograms, a phase compensation film, and a grating for PS-DPP (Phase-Shift Differential Push-Pull) method, we have developed a miniaturized integrated optical pickup for Mini Disc Player, and it got free of the tracking adjustment by rotating the integrated unit. The jitter of the MO (Magneto-Optical) signal reproduced by this pickup reached 9%.
