Magneto-optical disk recording apparatus
 A magneto-optical disk recording apparatus sequentially pulse-drive a plurality of semiconductor laser elements in a time-divisional manner so that spots of light are sequentially formed along a plurality of recording tracks of a magneto-optical disk with clock information recorded in advance along a plurality of recording tracks thereon. A magnetic modulating signal is generated by combining pieces of information desired to be recorded along the plurality of recording tracks so that a modulating magnetic field whose polarity is reversed in accordance with the magnetic modulating signal is applied to the plurality of recording tracks by means of a magnetic head.
