Abstract

If data stored in RAM (31) is of a data volume short of one cluster, deficit data is read out from a magneto-optical disc (22) to provide a data volume corresponding to one cluster. Data recorded on the magneto-optical disc (22) is rewritten by means of the RAM (31) on the cluster basis under control of a system controller (29).
