ABSTRACT:
To provide a magneto-optical reading method of making the inclinations of the front and rear edges of a waveform of a reading signal formed on a magneto-optical recording medium to be read more symmetric by applying a reading magnetic field different in accordance with the direction of a recording magnetic field when reading the recording marks to which recording magnetic fields in different directions are applied for recording because the present ranges of the front and rear edges are previously determined.
