ABSTRACT:
A method for overcoming aging of a magnetooptical recording medium (MEMOI) including at least one magnetic layer (CMI) covered by a layer of alumina (DIELI.sub.2) that is transparent to light. In order to improve the resistance to magnetic aging of the magnetooptical recording medium (MEMOI), this medium is subjected to annealing at a temperature in the vicinity of 200.degree. C., immediately after the medium is being deposited in a vacuum at ambient temperature. The invention is applicable to magnetooptical disk memories.
