Abstract

PURPOSE: To prevent write information from being lost by performing reset or counting by control from a host device, holding a counted result, and displaying it for a long period.
CONSTITUTION: By closing a switch 6 by indication from the host device, a counter 4 is reset, and by closing a switch 7, the counter 4 counts up by one. The count value of the counter 4 is held at the counter 4 for a long period, and also, it is displayed. Therefore, an operator can recognize the display of the counter 4 easily. In such a way, it is possible to improve the quality of a medium to a constant level in data management, and furthermore, to prevent the data from being lost.
