ABSTRACT:
In a computer system equipped with a magneto-optical disk drive having high data density, and therefore lengthy format times, and also requiring an erase step before each write operation, a system and method for decreasing user waiting time is provided. The system and method format the disk on a continuous basis during "disk-idle" periods rather than all at once. The system and method also erase disk portions belonging to deleted data in advance during disk-idle periods, so they are ready for the next write operation.
