发明名称 Magnetic head with large cross-sectional area core for use with magnetically induced super resolution medium and magneto optical recording apparatus
摘要 A magneto-optical recording apparatus for recording information in a magnetically induced super resolution medium (e.g., magneto-optical disk) comprising a magnetic head having a magnetic core whose sectional area along a plane parallel to a surface of the magnetically induced super resolution medium is larger than 0.08 mm2, a heating section for heating the recording layer of the magnetically induced super resolution medium, and a recording section for recording the information in the recording layer of the magnetically induced super resolution medium by driving the magnetic head and heating the recording layer using the heating section. Consequently, both the sensitivity to the recording magnetic field and reproductivity of high-density bits of the magnetically induced super resolution medium can be improved.
