ABSTRACT:
A recording and reading method and device of magneto-optical memory elements are provided to record and read an information signal to and from the magneto-optical memory elements, which contain at least two magnetic layers that are magnetically coupled, by means of a light-intensity modulated overwriting method employing a recording magnetic field and an initializing magnetic field feature is included for applying the initializing magnetic field to the magneto-optical memory elements at least one time between the point of time when moving the magneto-optical memory elements to a recording or reading position, finishing a reading or recording, and ascertaining the selected operation such as recording or erasing and the point of time when subsequent recording begins such that the initializing magnetic field is not applied at the same time as the recording magnetic field.
