  • Patent number: 5757735
    Abstract: In a magneto-optical recording method and, more particularly, a bit position recording method, laser beam intensity is pulse-modulated between high and low levels according to data to be recorded. The modulated laser beam is radiated on a recording medium under the presence of a bias field. High-level emission time of the laser beam is shortened at the inner portion of the medium, and is prolonged at the outer portion. Low-level intensity of the laser beam is decreased at the inner portion of the medium, and is increased at the outer portion, thereby increasing C/N ratio upon reproduction.
