Abstract:
A method for recording information on a magnet-optical recording medium, the method comprising the steps of:irradiating a pulsed light beam onto the recording medium to record a magnetized mark; detecting a bit inversion in the data to be recorded; applying a pulsed magnetic field to the recording medium when the bit inversion occurs in the data to be recorded, and reducing the energy level for generating the pulsed magnetic field by utilizing a reverse magnetic field generated by the magnetized mark that was previously recorded just before a present magnetized mark in the magnetic recording layer so that the energy level for generating the pulsed magnetic field for recording the present magnetized mark becomes smaller than the energy level that was used for generating the pulsed magnetic field for recording the previous magnetized mark when recording the present magnetized mark in the polarity that is opposite to the polarity of the previous magnetized mark.
