In an over-write capable magnetooptical recording method and, more particularly, a bit position recording method, and a recording apparatus used therefor, a 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...http://www.google.de/patents/US5128910?utm_source=gb-gplus-sharePatent US5128910 - Magnetooptical recording method and apparatus used therefor
