<p>A magneto-optical head assembly for a reflection type magneto-optical memory apparatus which uses a laser beam for recording, retrieving, and erasing data on a recording medium comprised of a vertical, magnetic, and anisotropic thin film, wherein the light beam emitted from said head assembly is guided to a fixed position on said recording medium by a light detection apparatus for receiving a control signal, and by a separate light detection apparatus for receiving a data signal.</p><p>And wherein a beam splitter, to which has been applied a multicoated thin film dielectric body capable of increasing the Kerr rotation angle of the laser beam reflected from the recording medium, is positioned in the optical system through which the laser beam passes.</p> |
