Abstract:
High density magneto-optical disk recording by superresolution technique is described. The focused spot size on the recording medium is reduced to 80% that of a conventional optical recording by setting the double rhomb prism in the collimating beam, which improves the light power loss. The readout signal degradation affected by focused beam sidelobes is suppressed by spatially extracting the main lobe region from reflected light using a slit. The linear recording density has been improved to 1.2 times as high as that for a conventional optical recording.
