ABSTRACT
The erase process in a directly overwritable magneto-optical material is shown to be a domain collapse dominated process, not a reversed domain growth process as previously suggested. The results of two experiments which support this conclusion are described. The first is a static evaluation of the residual domains of unsuccessful erase attempts. The second is actual high-speed observation of the dynamic process itself. Both experiments show that erasure in this material results from collapse of the previously written domain.
