摘要： A magneto-optical data recording system comprises magnetic field pulse applying means for applying to a magneto-optic recording medium a magnetic field pulse of a polarity corresponding to code data to be recorded, and means for heating the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to be recorded. During recording, the magnetic field pulse applying means applies a magnetic field pulse of a polarity corresponding to code data along a track of the recording medium and the heating means continuously heats the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to thereby directly overwrite the code data. The magnetic field pulse applying means includes a magnetic coil driven by code data from a source of code data (data generator). The heating means includes an optical head which comprises a source of laser beam driven by a laser driver and an optical system which focuses the laser beam from the source of laser beam as a small light spot onto the recording medium.

摘要： A magneto-optical disk which has a circular disk form and comprises a substrate provided with information pits and a guide groove, a recording medium layer provided on the substrate, and a protective layer formed of at least one thin film on the medium layer, in which the surface of the protective layer is minutely roughened to have a concave rough pattern and not to substantially protrude beyond a reference level composed of the outermost surface portions of the protective layer. When the magneto-optical disk is subjected to recording by a CSS system using an air floating magnetic head conforming to high-frequency recording in a magnetic field modulation type recording, which is one of methods of overwrite recording on magneto-optical disks, the minute concave rough pattern formed on the surface of the disk substrate prevents such troubles as adhesion of the magnetic head to the surface of the disk and collision between the disk substrate being rotated and the head.
