A magneto-optical head for magneto-optical writing and reading systems having an improved construction for a field modulating coil and a miniature objective lens, and a method of manufacturing the magneto-optical head. The magneto-optical head is mounted at the end of a slide-arm movable over a magneto-optical recording medium by hydrodynamics and includes: a lens mounted at the end of the slide-arm, for focusing incident light to form a light spot on the magneto-optical recording medium; a coil member including at least two stacked coil layers, and an insulating layer interposed between adjacent coil layers for electrically insulating the adjacent coil layers from one another, the stacked coil layers being planar coils with a spiral structure and having electrical contacts for electrical connection therebetween; and a connection member interposed between the lens and the coil member, for connecting the coil member to one side of the lens, facing the magneto-optical recording medium, and for electrically connecting the coil layers to an external power supply. The coil member is manufactured using a semiconductor fabrication process.
