Abstract:
A magneto-optical head for a magneto-optical writing and/or reading system capable of writing information on a magneto-optical recording medium by field modulation and optically reading information from the magneto-optical recording medium, the magneto-optical head being mounted at the end of a slide-arm movable over the magneto-optical recording medium by hydrodynamics, the magneto-optical head comprising:a lens mounted at the end of the slide-arm, which focuses incident light to form a light spot on the magneto-optical recording medium; a coil member comprising stacked coil layers, and an insulating layer interposed between adjacent ones of the coil layers that electrically insulates the coil layers from one another, each of the coil layers being planar coils with a spiral structure and comprising electrical contacts for electrical connection therebetween; and a connection member interposed between said lens and said coil member, which connects said coil member to one side of said lens, facing the magneto-optical recording medium, and which electrically connects the coil layers to an external power supply.
