摘要

In an IC memory card control system including an IC memory card and an IC memory card control apparatus to which the IC memory card is detachably mounted to store therein management information as well as data, the management area of the IC memory card is provided with an identification area into which are written an occupation code indicative of recording of the data in the data area and a recording code indicative of an abnormal recording of the data in the data area. The IC memory card control apparatus provides such a control that when writing the data into the data area, prior to data writing, the occupation code and the recording code are written into the identification area in their significant states, and after having completed the data writing the recording code is absolved from the significant state.
