In the search for a directly overwritable magneto-optic recording system, that based upon the magnetic field modulation method looks quite favorable. This approach also enables submicron domains to be written, so increasing attainable storage densities. Here we report on the results of such field modulation studies performed in situ using our magneto-optical scanning laser microscope (SLM). Bit patterns were recorded in TbFeCo films by continuous laser irradiation coupled with the application of an alternating magnetic field supplied by a small, purpose built electromagnet having a peak field of approximately 4 kOe. The recorded domain structures were then imaged using the SLM in its polar Kerr mode. Recorded patterns were overwritten and the resulting bit patterns observed.
