ABSTRACT:
An optical integrated device for a reproducing head for a magneto-optical record includes two devices formed on separate substrates. A first device includes a polarization detecting optical system, and a second device includes a polarized light source and photoelectric conversion means. The optical integrated device further includes link means for linking the first and second devices in proximate or close contact.
