Abstract:
A recording method for recording information on a magneto-optical recording medium by radiating a recording light beam onto the medium while applying a magnetic field in a recording direction to the medium, the method comprising:assigning one bit of information to a combination of a magnetic domain magnetized in the recording direction and a magnetic domain magnetized in the direction opposite to the recording direction, or to a combination of two magnetic domains magnetized in the direction opposite to the recording direction; andadjusting sizes of the domains such that, when at least two bits of information each corresponding to the combination of the magnetic domain in magnetized in the recording direction and the magnetic domain magnetized in the opposite direction are recorded in series, the domain magnetized in the recording direction for the first bit of the at least two bits is shorter than the domain magnetized in the recording direction for a bit contained in bits other than the first bit of the at least two bits.
