ABSTRACT:
After a laser beam of a high-level laser beam is applied to a multilayer magneto-optical recording medium to record information thereon, a laser beam of a laser power lower than the laser power of a reading laser beam is applied or substantially no laser beam is applied for a period of time .tau..sub.0. If one channel clock period or the period in which the high-level laser beam is of the second laser power is applied is .tau..sub.w, then the ratio R=(.tau..sub.0 /.tau..sub.w).times.100 is selected to be in the range from 15 to 70%.
