Patent ID: 7161876

Claim:
A recording method for recording information in a recording layer of a magneto-optical recording medium by forming a recording magnetic domain in the recording layer by heating the recording layer by irradiation with light and applying a recording magnetic field to the recording layer, the recording method comprising: forming a recording pattern in the recording layer, the recording pattern including a mark having a length greater than 0.5 μm and less than or equal to 2.2 μm, wherein a reproducing layer and the recording layer are provided on the substrate of the magneto-optical recording medium; wherein during reproduction or transcription, the recording magnetic domain recorded in the recording layer is transcribed onto the reproducing layer in a vertical magnetization direction, and a shrink force is subsequently applied to the recording magnetic domain transcribed onto the reproducing layer; a laser light source for recording and reproduction has a wavelength of about 660 nm and an NA of about 0.60, and the laser light source is arranged to supply a constant polarized light onto a recording medium; and the laser for recording and reproduction has a pulse light having a duty in a range of about 30% to about 50%.
